Checking the sensor No. 1 air temperature at the inlet
1. Disconnect a wire from the negative plug of the storage battery.
2. Remove the sensor.
3. Using an ohmmeter, measure the resistance between the terminals "A - B" sensor.
If the resistance value is out of range, replace the sensor.
Checking the boost pressure sensor
1. Set the ignition key to position "ON" (engine off).
2. Connect the scanner to the diagnostic socket and check the signal voltage of the boost pressure sensor (MAP PID).
- Signal voltage - about 1.65 V
If the sensor signal voltage is not as specified, check the wiring harness. If the wiring harness is OK, replace the sensor.
3. Start the engine and warm it up to normal operating temperature.
4. Check boost pressure sensor signal voltage (MAP PID) at idle.
- Signal voltage - about 1.65 V
If the sensor signal voltage is not as specified, check the wiring harness. If the wiring harness is OK, replace the sensor.
