cable (PIN 3): if not OK, restore the cable harness. If it is OK, check the continuity of the
green cable (between the sensor connector PIN 3 and the ENGINE PIN 32) and restore the
cable harness.
WARNING
The control unit does not detects the following malfunctions of the lambda probe circuit according to
the signal: interrupted circuit, shorted to ground or sensor malfunction (for example non variable volt-
age). In case of fault indication, carry out the following troubleshooting.
Troubleshooting
•
Check circuit continuity from probe connector (PIN 1 and PIN 2) toward the probe: replace
the lambda probe if there is no continuity; if there is continuity, check the sensor connector
and the Marelli control unit connector: If not OK, restore. If OK, check continuity between
the ENGINE connector PIN 22 and PIN 10 and restore the cable harness.
