Electrical system
•
if shorted to positive: with key set to ON, disconnect the sensor connector and measure PIN
1 voltage on the cable harness side (grey cable): if there is voltage (5 or 12 V), restore the
cable harness; if there is not, replace the lambda probe.
Lambda probe heater P0130 - shorted to positive / open circuit, shorted to negative.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 11 of connector B (BLUE).
If the circuit is open, shorted to negative: voltage equal to zero has been detected.
Troubleshooting
•
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.
•
If the circuit is open, shorted to negative: check the sensor connector: if it is not OK, restore;
if it is OK, check the continuity towards the sensor from PINS 3 and 4: if it is not OK, replace
the sensor; if it is OK, check the continuity of the white cable between the sensor connector
and PIN 11 of connector B (BLUE) of the control unit: if it is not OK, restore the cable harness;
if it is OK, it means that the white cable is in continuity with the ground cable and it is nec-
essary to restore the cable harness.
