Troubleshooting
•
Check the sensor connector and the ENGINE connector of the Marelli control unit.
NOTES
No error is detected if the sensor does not work correctly or the control unit connector or sensor terminals
are rusty: then use the diagnostic tool to check if the temperature indicated is the same as the engine
temperature. Check also that the sensor electrical characteristics are observed: replace the sensor if
not OK; if it is OK, check the sensor connector and the Marelli control unit connector.

intake air, used to calculate the oxygen, to opti-
mise the required fuel quantity for the correct com-
bustion
