Electronic control system (TCCS)
The location of the electronic control unit ECM in the car Electronic control unit (ECM) receives signals from various sensors that monitor changing engine operating conditions, such as the amount of air entering the...

ECM self-diagnosis system
The ECM contains a built-in self-diagnostic system that detects and recognizes faults. When a malfunction occurs, the control lamp lights up "check engine", the fault is identified and a diagnostic code is stored. Alarm...

Coolant temperature sensor
Dependence of the resistance of the coolant temperature sensor on temperature Location of the coolant temperature sensor on a four-cylinder engine The coolant temperature sensor is a thermistor that changes its...

Oxygen sensor
Attention! Use only a pointer voltmeter, as it is necessary to observe the oscillation of the pointer. Cars have one or two oxygen sensors. On models with two sensors, the main oxygen sensor is installed in front of the...

Throttle position sensor
The throttle position sensor is located at the end of the throttle shaft in the throttle body. By measuring the output voltage of the throttle position sensor, the ECM controls the amount of fuel delivered in accordance...

Air flow meter (only 3VZ-FE V6 engines)
Checking the resistance between the contacts of the air flow meter connector on the 3VZ-FE V6 engine The air flow meter measures the amount of air entering the engine. Based on information from the air flow meter, the...

MAF mass air flow sensor (engine 1MZ-FE)
Checking the resistance with a sensor for measuring the mass of the air flow when the engine warms up (engine 1MZ-FE V6) The mass air flow sensor is located in the intake duct. The operation of the sensor is based on...

Absolute pressure sensor (four-cylinder engines)
Dependence of the change in the resistance of the temperature sensor of the air entering the engine on temperature The intake manifold absolute pressure sensor induces a signal from 4 V in the absence of vacuum to 0.5 V...

EGR temperature sensor
EGR temperature sensor (waste gas re-burning systems) installed near the EGR valve. 1. To test the sensor, disconnect the electrical connector from the sensor and measure the resistance of the sensor at various...

Vehicle speed sensor
Vehicle speed sensor (VST) located on the back of the gearbox.

Knock sensor (only with V6 engines)
The knock sensor detects knock in the engine cylinders and sends a control signal to the ECM, which reduces the ignition timing by an amount that excludes knocking in the engine cylinders. 1. The knock sensors are...

Camshaft position sensor (engine 1MZ-FE)
The camshaft position sensor is located in the cylinder head near the toothed belt guard. 1. Using an ohmmeter, check the resistance of the camshaft position sensor, which should be between 835 and 1600 ohms depending...

Crank angle sensor (1MZ-FE engines)
An arrangement of the gauge of an angle of rotation of a cranked shaft on the engine The crank angle sensor is located in the front cover near the crankshaft pulley.

Induction air supply system to the engine (ACIS) — examination
Location of elements of the induction air supply system to the engine The induction engine air supply system changes the direction of air flow in the intake manifold depending on the engine speed. The system actuator is...

Induction air supply system to the engine (ACIS) — replacement
Attention! If your radio has an anti-theft code, check that you have the pairing codes before disconnecting the battery. Attention! On models since 1993, the airbag system is disabled if the battery is disconnected for...

Exhaust Gas Re-burning System (EGR)
Scheme of operation of the exhaust gas re-burning system To reduce the emission of nitrogen oxide into the atmosphere, along with the exhaust gases, part of the exhaust gases through the EGR valve enters the intake...

Crankcase ventilation system (PCV)
To reduce the release of unburned hydrocarbons from the crankcase into the atmosphere with a sealed engine, crankcase gases and oil vapor are drawn from the crankcase into the air supply path to the engine and are...

Exhaust system catalyst — general information
Removing the catalyst together with the exhaust system from under the car If there is damage or dents on the catalyst housing, it must be replaced It must be periodically checked that there is sufficient air gap between...
