Faulty sensor or cabling, interference on the signal
Troubleshooting
•
Disconnect the sensor connector.
•
Verify, with the key ON, the voltage between sensor PIN 1-3.
•
If no voltage is detected, check the continuity of the cabling between sensor PIN 1 and
instrument panel connector PIN 13.
•
Carry out the check procedure on instrument panel connector PIN 13.
•
If the cabling is intact, check for continuity with the sensor PIN 3 ground.
•
Check continuity of the cabling between sensor PIN 2 and instrument panel connector PIN
17.
•
Carry out the check on instrument panel PIN 17.
•
In the event that these checks have not detected the fault, replace the sensor.
