The last century in the automotive industry has become very famous for many works of art in the automotive industry. It is especially worth noting the Japanese car Toyota Corolla, which to this day is at the hearing of motorists. These cars are famous for their reliability and allow you to be sure that the car will not let you down at the right time. It is especially worth stopping and talking about the Toyota Corolla engines, which differed and are distinguished by their performance, quality and "survivability".

History of engines of twelve generations

From 1966 to the present day, the Japanese have developed and produced twelve generations of one model and achieved incredible results in the automotive industry. Let's look at how the power units of this model have developed and changed for almost 50 years.

The first model of the car was called "Sprinter". This car was released with one 1.4-liter engine option. It has proven itself to be quite reliable. workhorse- it was precisely because of this that the car was given such a name - a sprint car, the resource of the power unit was so great that it would be enough to go around Earth at least once without any breakage. In addition, its agility and relatively low fuel consumption, as well as the simplicity of their structure, were very interested in motorists of that time. This generation of the engine bore the index "T1".

Six years have passed, the Sprinter has been heavily restyled, especially in terms of body materials and interior trim, but apart from that, Toyota's engineering department also hooked on the power unit. Since 1972, the car has become the owner of two completely new power units with a volume of 1.4 and 1.6 liters. The last of which opened the way for the second generation under the index "T2". This power unit was distinguished by the fact that it had 2 valves for each cylinder. The dynamics of the car has grown significantly with the advent of the 1.6-liter engine.

The third generation was not pleased with the appearance of new engines, however, the fourth generation, which appeared in 1979, pleased many motorists, both in Japan and in neighboring countries. For the first time, the engines on the Corolla were equipped with an injection system.

The fifth generation was not long in coming. The year 1983 has come. Power units have been significantly improved. There was a new variant with a volume of 1.8 liters, it is worth noting that this was the first diesel engine on the Corlla. The Japanese indexed it as "1C". In the international automotive market, the Japanese could boast of an electronic fuel injection system, which significantly increased engine performance, but reduced its service life. However, do not be sad, in the future with the advent of new generations this problem was eliminated by the use of denser and higher quality metals.

Years passed and in 1987 the Toyota concern developed more modern and more powerful engines. The turbocharged 4A-GZE engine, which had 165 horsepower, became famous. This power unit was of great interest to the younger generation, since its power was quite large, and the design of the car itself made it possible to squeeze almost everything out of it to the last drop of power. In addition to the most powerful engine, the most economical engine of this generation with a volume of 1.3 liters was also of interest. He could not boast of his agility, but he was an ideal assistant in everyday affairs. The resource of its performance was incredibly large, and it was almost impossible to kill the engine, and fuel consumption was pleasing to the eye - the car ate no more than 6 liters per 100 kilometers. A great option for accomplished men who wanted to have a reliable car and a minimum of problems with it.

Further, until the eighth generation, until 1998, nothing interesting happened. However, in this - 1998 - Toyota first released a car engine with an aluminum block and cylinder heads - this made it possible to kill two birds with one stone - to reduce the overall weight of the car and increase its service life. This engine model wore the index "1ZZ-FE".

The ninth generation has made some adjustments to the management of power units. The appearance of more modern systems and computers inside the car made it possible to increase the efficiency of existing engines by new level. This, in turn, significantly increased interest in this car model.

The next generation of Toyota, which began in 2006, significantly increased the range of powertrains from the existing 5 to 7 models. There are two new engines - one diesel - amazing in terms of fuel consumption and the second - gasoline - a two-liter engine with good power and agility.

And finally, the twelfth generation, whose production began in 2012. Something new, modern appeared in the model range of power units - a 1.5-liter hybrid engine was installed in Corlla. Its fuel consumption pleased and pleases the eye of people. Only 3 liters per 100 kilometers is an incredible result that Japanese engineers were able to achieve. In addition, new engines with the indices "1NR-FE", "2ZR-FAE" and "1NZ-FE" will appear.

To date, the Toyota automobile concern is developing a new 13th generation Corlla, which, I hope, will please many motorists with its innovations and changes in better side. Although it could be much better - the company is engaged in the production of engines for many Chinese and Korean manufacturers. Its engines are on a par with such well-known German manufacturers as Mercedes and Audi, which are famous for their quality and reliability in operation.

Toyota Corolla 1.6 engine liters is one of the most popular and successful engines on Toyota Corolla. The motor model according to the manufacturer's internal classification is 1ZR-FE. This is a gasoline aspirated, 4-cylinder, 16-valve engine with a timing chain drive and an aluminum cylinder block. Toyota designers tried to make sure that the consumer does not look under the hood at all. The motor resource and reliability of the power unit are very decent. The main thing here is to change the oil on time and pour high-quality fuel.

Toyota Corolla 1.6 engine device

The Toyota Corolla 1.6 engine has absorbed all the best developments of previous generations of engines from the Japanese manufacturer. The motor has advanced Dual VVT-i variable valve timing systems, a Valvematic valve lift system, and the intake tract has a special design that allows you to change the air flow rate. All these technologies have made the motor the most efficient power unit.

Toyota Corolla 1.6 engine cylinder head

The cylinder head is a pastel for two camshafts with “wells” in the center for spark plugs. The valves are arranged in a V-shape. A feature of this engine is the presence of hydraulic lifters. This means you don't have to adjust the valve clearance. The only problem is the use of low-quality oil, in which case the channels can be clogged and the hydraulic lifters will stop performing their function. In this case, a characteristic unpleasant sound will come from under the valve cover.

Toyota Corolla 1.6 engine timing drive

Toyota designers and engineers decided to make the chain drive of the engine as simple as possible, without all kinds of intermediate shafts, additional tensioners, dampers. In addition to the crankshaft sprockets and camshafts, only the tensioner shoe, the tensioner itself and the damper are involved in the timing drive. Timing diagram below.

For the correct alignment of all timing marks, there are links painted in yellow-orange color on the chain itself. When installing, it is enough to align the marks on the camshaft and crankshaft sprockets with the painted chain plates.

Technical characteristics of the Toyota Corolla 1.6 engine

• Working volume - 1598 cm3
• Number of cylinders - 4
• Number of valves - 16
• Cylinder diameter - 80.5 mm
• Stroke - 78.5 mm
• Timing Drive - Chain
• HP power (kW) - 122 (90) at 6000 rpm in min.
• Torque - 157 Nm at 5200 rpm. in min.
• Maximum speed - 195 km / h
• Acceleration to the first hundred - 10.5 seconds
• Fuel type - gasoline AI-95
• Fuel consumption in the city - 8.7 liters
• Combined fuel consumption - 6.6 liters
• Fuel consumption on the highway - 5.4 liters

In addition to the timely replacement of high-quality oil, carefully monitor what you fill the car with. If you do not pour anything into the engine, then the engine will delight you for many years. In practice, the motor resource is up to 400 thousand kilometers. True, repair dimensions for the piston group are not provided. Perhaps one more weakness are sudden changes in temperature. If you overheat the engine, then the cylinder head or even the block may be deformed, and these are significant financial losses. The 1ZR-FE engine has been installed on almost all 1.6-liter Corollas (and other Toyota models) manufactured since 2006-2007.

The Toyota Corolla class C passenger car is produced by the well-known automotive corporation from Japan. The trademark appeared for the first time in 1966 and has since gained popularity all over the world. Corolla in 1997 became the best-selling brand on the planet, thanks to which he got into the Guinness Book of Records. The Japanese model managed to surpass the Volkswagen Beetle (beetle). In less than half a century, sales have exceeded 39 million vehicles. Over the years, Corolla has undergone many changes along the way.

The name of the model in Latin means "small crown". Toyota Corolla, in addition to Japan, is produced in Canada (Ontario, Cambridge), Brazil (Indaiatuba, Sao Paulo), India (Bangalore), China (Tianjin), England (Derbyshire), Australia (Victoria), Venezuela, Turkey, Thailand, Taiwan, South Africa, Philippines, Pakistan, Malaysia and Indonesia. In the United States of America (California, NUMMI), this brand ended in 2010.

The chassis and engines of the Toyota Corolla have the code "E", which means they belong to the Corolla family. At first it was mainly rear-wheel drive cars, then there were cars with all-wheel drive and front-wheel drive. Almost immediately with the appearance on the market, this model began to compete with the Nissan Sunny.

The first Toyota Corolla was born in 1966. The brand had rear-wheel drive, the engine was located longitudinally. A special feature of the car were round headlights. This arrangement remained until 1984. This year, the first Corolla equipped with front-wheel drive appeared on the automotive market.

From the moment of its birth to 1997, the car was produced in five body solutions:

• station wagon;
• liftback;
• five-door hatchback;
• three-door hatchback;
• sedan.

Toyota Corolla 1966 to 2014

The fifth generation of the model, which appeared in 1984, retained rear-wheel drive for the station wagon and three-door hatchback, while other options received front-wheel drive. In 1987, the sixth generation of this car with the E90 body appears on the automotive market. Despite the obsolete design, excellent anti-corrosion coating, excellent build quality has turned this generation into one of the most popular in the world. The eighth generation Corolla launched in 1997. The EE110 body was represented by the following varieties:

• station wagons;
• three-door liftbacks;
• five-door liftbacks;
• sedans.

Toyota corolla engines were classics of their kind in the world of mechanical engineering.

Modifications of a popular car

The Corolla Market Center was originally called the Toyota Public Store in Japan. Here, Toyota Publica cars were offered to customers. The Corolla was sold almost at the same time as the rebranded Sprinter. For many years there have been high-quality additions: the twin Sprinter Marino and Corolla Ceres (hardtop body), sports versions of the Sprinter Trueno and Corolla Levin.

Toyota Corolla FX GT

Under the Toyota brand, the Corolla FX with a hatchback body was released. This brand later became known as Corolla RunX. Then the Corolla ZZE128 appeared on the market. The Corolla Verso minivan was originally intended for the European market. This model has an option for Japan - Corolla Spacio, the production of which has been suspended since the tenth generation.

A variation of the Corolla, the Rumion, is known in America as the Scion xB. On the E140 and E120 platform by marketers North America Toyota Corolla Matrix was released. Toyota Australia produced station wagons Corolla TE72. In Australia, the five-door station wagon was sold in the automotive market as the Corolla Seca. The name traditionally passed to the new generations of five-door models.

At Toyota, the first model with front-wheel drive was the Corolla Tercel, which rolled off the factory assembly line in 1980. Some time later, on the basis of Tercel appeared Corolla II hatchback. The resource of the Toyota Corolla engine provided good speed, reliability and a long period of operation.

E10, first generation

Toyota Corolla Body E10

The presentation of the first car Toyota Corolla took place in the Land of the Rising Sun in October 1966. The ninety-inch wheelbase model was intended for domestic sales. It was equipped according to the usual classical scheme with rear-wheel drive.

The prototype was equipped with a motor, the working volume of which was less than a liter. In those years, larger displacement Japanese engines earned the manufacturer an increase in tax. The company nevertheless decided to increase the most important indicator. The longitudinally mounted engine K had a volume of 1.1 liters and a power of seventy-three horsepower. He worked on gasoline and could reach speeds of up to one hundred and thirty-five kilometers per hour.

Three years later, the company increased the volume of the engine to 1.166 liters. This decision benefited the car: it was willingly bought. Engines could be equipped not only with a single-chamber, but also with a two-chamber carburetor. For a 1.1 liter engine - K-V carburetor, for 1.3 liters - 3K-V. When compared with single-chamber, the increase in power actually amounted to 13 horsepower. For that time it was a significant increase. Both engines had four cylinders and eight valves. The gearbox could be either a two-speed automatic or a four-speed manual.

The Toyota Corolla Sprinter model appeared on the automotive market two years after the first presentation. It was made in a fastback body and was offered to customers only through the Toyota Auto Store, the firm's dealership in Japan.

E20, second generation

Toyota Corolla body E20

In 1970, in the month of May, the first version of the E20 appeared - the second generation Corolla with a wheelbase of 91.9 inches. The body of this model has become more streamlined, the dimensions have slightly increased. Unlike the first generation, this version was presented to customers in two versions. The engine capacity of one of them, OHV-1400T, was 1.4 liters with a capacity of ninety horsepower. The volume of another engine, OHV-1600 2T, is 1.6 liters, and the power - first one hundred and two horsepower, later - increased to one hundred and fifteen horsepower. Accordingly, the cost also differed. Since this year, the production of Sprinter and Corolla has already differed in finishing and metal processing methods. In March 1972, an improved version of the Corolla Levin appeared, equipped with a 2T engine with 2 camshafts. There were no changes in the suspensions, the lights, radiator grille, direction indicators and headlights became different. Body protection against corrosion was at a low level, so sales declined.

In Australia, the second generation introduced the KE20 station wagon, equipped with a 3K engine, and a two-door sedan. These models had a single brake system with drums at the rear and brake pads at the front. In New Zealand, the KE20 model, a four-door Corolla, appeared on the car market.

E30, E40, E50, E60 third generation

Toyota Corolla body E30

The debut of the third generation in April 1974 coincided with the oil crisis. Demand for the Corolla, especially in the US, began to grow as it was a practical and economical model. For the first time in the history of the family, the company has taken the lead in terms of production of these machines.

Body indices for cars sold in different countries differed significantly:

• in Japan - E30, 35, 36, 37, 50, 51, 52, 53;
• in Europe - E30;
• in the USA - E31, 37, 38, 51;
• in Australia - KE30, 35, 38, 55.

The E51 and E50 indices fell on brands with a liftback body, under the E60 and E40 indices they went to sell the Toyota Sprinter. The most affordable modification of all is a two-door sedan equipped with a 3K engine, which had a volume of 1.2 liters with fifty-five horsepower and a standard MCP-4. The rear suspension has undergone changes, instead of springs, springs have appeared. The power of the engines was reduced due to the installation of a catalytic converter.

The most common engines with a volume of 1.2 and 1.6 liters gave power, respectively, of 55 and 75 horsepower. In a number of countries, there was a 1.3-liter engine with a power of 60 hp. In Japan, the 2T-G engine (1.6 l, 124 hp) was sold. The body remained unstable to corrosion. A little later, four-door sedans appeared on the market.

E70 fourth generation

Toyota Corolla body E70

The 4th generation model appeared in 1979, when approximately 2300 of these cars were produced in one day. In Japan, a sales record was set.

For the US market, the 3T-C engine (1.8 l, 76 hp) appeared. In 1983, it was replaced by a more economical 4A-C engine with an aluminum cylinder head (1.6 liters, from 70 to 90 hp). After him, the corporation began to use aluminum BC heads. The 1.2 liter engine was replaced by another (1.3 liter, 65 hp). The gearbox did not change at first. A four-speed automatic appeared in 1982.

Front brake mechanisms became disc. An anti-roll bar has been added to the front suspension. An innovation was the power steering, brake booster. Since 1981, round headlights have become rectangular.

E80, fifth generation

Toyota Corolla body E80

The presentation of the fifth generation took place in May 1983. Five-door hatchbacks and sedans appeared on the market. For the European market in 1984, another five-door hatchback was created. The engines remained the same, as did the MKP-5. The automatic box could be not only with four, but also with three steps.

For the first time they began to sell cars with a diesel engine (1.8 liters, 58 hp). Made independent rear wheel suspension. The drive has become front. For the first time on a Corolla, the engine was placed across. In sports models, a 4A-GE engine with a volume of 1.6 liters and a power of up to 130 hp was used. With. The station wagon with all-wheel drive was sold only in the United States.

E90, sixth generation

Toyota Corolla body E90

The debut of the sixth generation took place in May 1987. Only modifications with front or all-wheel drive remained. The motors remained both carburetor and injection. The 4A-GE engine (1.6 l) was upgraded in 1990, which made it possible to increase its power to 135 hp. With. In Europe, the 1C diesel (1.8 l) was popular, the power of which increased to 67 hp. With.

All Corolla suspensions are independent, while the station wagon had a continuous rear axle. In 1989, a sedan was equipped with all-wheel drive for the US market. Everywhere service maintenance Japanese brands - at a good level.

E90, seventh generation

Toyota Corolla 1993 onwards

The seventh generation was introduced by the company in 1991. The car has become more dynamic and bigger. The most popular engines are 7A-FE 1.8 liters and 4A-FE 1.6 liters. In Japan, sports versions with up to 168 hp were sold. With. In Europe - only injection engines and an atmospheric diesel engine 2C with a capacity of 72 liters. With.

A three-door hatchback with all-wheel drive, a 7A-FE engine (1.8 liters, 118 hp) was considered a powerful brand. In the US market, there were only Corolla wagon and sedan.

E110, eighth generation

Toyota Corolla body 1995

In May 1995, the corporation introduced the eighth generation. Technically, the car has not changed. In 1997, the interior and exterior were slightly updated. In Europe, the car was awarded the title of "car of the year".

The car for the rally was equipped with a 3S-GTE engine, as well as an all-wheel drive transmission. Since 1999, a series of ZZ-FE motors has been introduced. In the US, the 1ZZ-FE engine has gained particular popularity in the Toyota Avensis.

E120, E130, ninth generation

Toyota Corolla 2001 onwards

The ninth generation started in 2001 in Frankfurt. New brand specially designed for Europe. There are a lot of bodies: a high-capacity station wagon, a sedan, three- and five-door hatchbacks, just a station wagon. There was a novelty with a 1.8 liter engine with a capacity of 192 hp. With. and MKP-6 (Toyota T-Sport). Diesel received a power system.

In 2004, moldings, optics, bumpers were updated, airbags appeared on the side. In the used car market, this generation is still in demand.

E140, E150, tenth generation

The most popular car on the planet was destined to become the representative of the tenth generation. Forty million copies sold. The car has become wider and longer, more economical and comfortable. The rigidity of the body has increased. At basic version- 15 inch wheels.

In the US, they sell a car with 1.8-liter gasoline engines. One is 2ZR-FE (132 hp) and 2ZR-FAE, which has a Valvematik system and has increased compression (140 hp). In America, there is a gearbox choice between a six-speed "mechanics" and a five-speed "automatic".

The base engine in Europe is Dual-VVTi (1.33 liters of gasoline, 99 hp). The second is the engine of the same design (1.6 liters, 122 hp). A novelty in Europe is the CVTi-S (Multidrive) variator.

E160, eleventh generation

Sales of these models began in May 2012 in the Japanese market. Sedan - Corolla Axio, wagon in the back - Corolla Fielder. A sedan with a 1NR-FE series engine has a volume of 1.3 liters, and 1NZ-FE - 1.5 liters. The engines have four cylinders.

Modifications are equipped with a CVT gearbox (stepless) and a five-speed manual transmission. Only with a continuously variable gearbox is a brand with all-wheel drive and a 1.3-liter engine available. Corolla Fielder is sold on the market with a 1.5 liter or 1.8 liter engine and a continuously variable transmission. The first version comes with all-wheel drive and front-wheel drive, the second has only front-wheel drive.

E170 for Europe

Toyota Corolla body E170

The release of the next generation of the legendary Toyota Corolla (Toyota Corolla XI) on the conveyors of Europe began in 2013. Despite this fact, officially the car belongs to the 2014 model year and carries a special body index E170.

The Corolla car presented on the Russian market is equipped with three types of gasoline engines, differing in power and cylinder capacity. In the Toyota technical documentation, they are assigned the following indices: 1NR-FE (cylinder displacement 1329 cc, power 99 hp or 73 kW), 1ZR-FE (cylinder displacement 1598 cc, power 122 hp or 90 kW) and 2ZR-FE (cylinder displacement 1798 cc, power 140 hp or 103 kW).

All engines have the same architecture: two camshafts in the head (DOHC - Double Over Head Camshaft), four valves per cylinder, plus the original Dual VVT-i valve timing system. The material of the blocks is a special aluminum alloy, from which, among other things, the walls of the wells are made.

Corolla E170 vehicles with a 1NR-FE engine are equipped with a 6-speed manual transmission.

The 1ZR-FE engine in the Russian market will be mainly offered for Corolla models with 6-speed manual, but its symbiosis with the Multidrive S variator is optionally possible.

There is only one transmission for the 2ZR-FE engine - a conditionally “seven-speed” variator.

On top of success

In October 2012, Toyota calculated the total volume of models sold in the automotive markets. It worldwide amounted to 74 million cars. In this figure - a significant share of the Corolla lineup.

Toyota Corolla owners are 2.47 million in the US, 1.4 million in China and 1.39 million in Europe. The figures speak of the great success achieved by the Japanese corporation.

How to pay for GASOLINE TWICE LESS

• Gasoline prices are rising every day, and the appetite of the car is only increasing.
• You would be happy to cut costs, but is it possible to do without a car in our time!?

But there is a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline! More about it

The engine resource of the Toyota Corolla is usually not on the list of advantages that the owners of these cars boast about. Usually, such motors have to be sorted out in the third hundred run.

History of Toyota Corolla engines

The Toyota Corolla has been leading its history since 1966. The engine was then a 1.4-liter, its reliability was commendable. The first injector was installed on the Corolla in 1979. By that time, there were already two engine options: 1.4 and 1.6 liters.

The first diesel engine in Toyota Corolla appeared in 1983 (1.8 liters).

The motor resource of the first Toyota engines was quite large.

Modern motors appeared in 2008 and lost this quality of their predecessors.

Engine 1ZZ-FE Toyota Corolla

The power unit, labeled 1ZZ-FE, began to be installed on Corollas in 1998. It belongs to the ninth generation of engines of the Japanese brand. This engine is a four-cylinder (in-line arrangement), 16-valve, volume of 1.8 liters. This is the first Toyota motor that was made of aluminum. Perhaps this is due to the decrease in its motor resource. All subsequent Toyota Corolla engines up to the modern one are its modifications.

Disadvantages of Toyota Corolla engines

The following disadvantages are characteristic of modern Corolla engines:

• High oil consumption. The problem is related to the occurrence of oil scraper rings. The problem was solved in 2005. 1.6 2008 car owners note that the problem is much less common.
• Increased engine noise, the appearance of a knock. The timing chain of Toyota engines stretches quickly enough and starts to make extraneous noise.
• Floating engine speed. With such a problem, it is recommended to clean the throttle.
• Engine vibration. This characteristic is often found and is considered the norm for Toyota Corolla. If the vibration increases, it is necessary to check the rear engine mount.

Motor resource of Toyota Corolla engine: owner reviews

Of course, what resource your car's engine will have depends on the attitude to the car and operating conditions. However, general trends are still visible. Toyota Corolla motors do not receive positive reviews in terms of long-term. In most cases, they require replacement after 200,000 km.

Often on the forums you can see that the Corolla motor is called "disposable". This characteristic is not far from the truth: the fact is that Toyota aluminum units are not officially subject to major repairs. Of course, it is possible to carry out some manipulations with them to extend the service life, some car services even offer such services, but such actions cannot be called a full-fledged capital.

Engines after 2005 are considered more reliable than units from the beginning of the 21st century, but the opinion about them in the auto community is still ambiguous.

How much does a Toyota Corolla engine cost?

The average cost of a motor for a Toyota Corolla is 75 thousand rubles. Acquisition of contract engines for such vehicles is possible and quite common.

Malfunctions and repair of the 1ZR-FE / FAE engine

These motors were presented to the public in 2007 and were considered as the successor to the unsuccessful ZZ series. The family consisted of 1.6 liter 1ZR, 1.8 liter. , 2.0 l. , as well as Chinese 4ZR, a working volume of 1.6 liters. and 5ZR 1.8 liters. Consider the youngest representative of the main lineup - 1ZR, this engine was designed to replace the motor. In the new 1ZR, to reduce the load on the sleeve, the axis of the cylinders does not intersect with the axis of the crankshaft, Dual VVT-i has been used, in other words, the system for changing the valve timing on the intake and exhaust shafts, at the same time, the Valvematic system has appeared, which changes the valve lift (range 0.9 - 10.9 mm), hydraulic lifters appeared and now you are not threatened with valve adjustment on 1ZR. By new tradition Toyota, the ZR engine is disposable, in an aluminum block, without repair dimensions, with all the consequences.

Toyota 1ZR engine modifications

1. 1ZR-FE - main engine, equipped with dual VVTi, compression ratio 10.2, power 124 hp. This motor was equipped with Toyota Corolla and Toyota Auris.
2. 1ZR-FAE - an analogue of 1ZR-FE, but together with Dual-VVTi, Valvematic is used, the compression ratio is increased to 10.7, engine power is 132 hp.

Malfunctions, 1ZR problems and their causes

1. High oil consumption. The problem is typical for the first ZR models, it is solved by filling oil with a viscosity of W30, instead of 0W-20, 5W-20. If the mileage is serious, then measure the compression.
2. 1ZR engine knock. Noise at medium speeds? Change the timing chain tensioner. In addition, the alternator drive belt can also make noise (whistle), change it.
3. Problems with idling. Swimming and other troubles are provoked by the throttle position sensor and the dirty throttle itself.

In addition, the pump on the 1ZR likes to leak, make noise and ask to be dumped after 50-70 thousand km, the thermostat often dies and the engine refuses to warm up to operating temperature, the VVTi valve can jam, followed by car dullness and loss of power. Nevertheless, these problems are not very common, the 1ZR engine turned out to be quite good, with a normal resource (+\- 250 thousand km) and with stable service, it does not cause problems for the owner.
