•
If shorted to positive: disconnect the probe connector and check the sensor correct resist-
ance: replace the sensor if not OK; if it is OK, restore the cable harness (Green/Red cable)
•
If circuit is open, shorted to negative: check circuit continuity from probe connector (PIN 3
and 4) toward the probe: if it is not OK, replace the probe; if it is OK, check the sensor
connector and the Marelli control unit connector: if it is not OK, restore; if it is OK, with key
set to ON and sensor connector disconnected, check if there is battery voltage at PIN 4: if
it is not OK, check the Pink/Brown cable continuity between the probe connector and the
auxiliary injection relay (No. 35 in the wiring diagram, placed in the front relay box, left side;
CHECK, however, the identification of the relay with the colour of the cables). If there are
also coil, lower and upper injector and secondary air errors, check the relay and its excitation
and power line; if there is voltage at PIN 4, check the Green/Red cable ground insulation
(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.
DIAGNOSIS INSTRUMENT: LOGIC ERRORS
Lambda probe P0134 - voltage without variation.
