Warning. Before performing repair work on a VAZ 2110 car to replace the TPS sensor, read the precautions for repairing the engine control system (see "Precautions when repairing the engine management system").
To carry out repairs you will need:
- multimeter (in voltmeter and ohmmeter mode);
- wire segments.
Examination
1. We prepare the car for work (see points 1 and 2 "Preparing the car for maintenance and repair").
2. We release the lock of the wiring harness connector from the TPS sensor.
Disconnect the connector from the TPS sensor.
3. Connect «negative» voltmeter probe to «mass» engine.
4. Turning on the ignition on the car, connect «positive» voltmeter probe to terminal A wiring harness connectors (pin numbering is printed on the block), and measure the supply voltage.
Note. The supply voltage at terminal A of the connector should be about 5 V. If the voltage is not supplied to the connector or it is less than 5 V, then the power circuit is faulty or the computer is faulty.
Warning. Turn off the ignition after the voltage measurement is completed.
Removing
1. Using a Phillips screwdriver, unscrew the two screws securing the idle speed controller to the throttle body.
2. Remove the sensor from the throttle axis. The connection of the sensor to the throttle body is sealed with a foam ring.
Recommendation. You can verify the malfunction of the TPS sensor by replacing it with a known good one.
Installation
1. We put the sensor on the axis of the throttle actuator.
Warning. For a properly installed TPS sensor, the leads should be directed towards the partition of the engine compartment.
2. Holding the sensor in a position in which the holes for the mounting screws are aligned with the threaded holes in the throttle body, turn the throttle drive sector until it stops.
Warning. If this cannot be done without turning the sensor housing, then the sensor is not installed correctly. Remove the sensor from the throttle shaft and install in a different position.
3. After making sure that the TPS sensor is installed correctly, we wrap the screws for its fastening and attach the wiring harness connector.
