•
Verify that there is no short to battery positive on sensor connector PIN 2 (corresponding to
control unit connector PIN 12); if there is a short, restore the cabling.
The circuit is open:
•
Disconnect the control unit connector and the sensor connector.
•
Verify continuity of the cabling between the sensor connector and the control unit connector:
Control unit PIN 11 - sensor PIN 1 and control unit PIN 12 - sensor PIN 2. Restore the cabling
if necessary.
•
If the cabling is intact and the error persists, proceed with the following checks.
Shorted to negative:
•
Disconnect the sensor connector and the control unit connector.
•
Check the sensor connector PIN 1 ground insulation. In the absence of insulation restore
the cabling.
•
Check the sensor connector PIN 2 ground insulation. In the absence of insulation restore
the cabling.
•
If PIN 1 and PIN 2 are insulated from the ground and the error persists, this means that there
is a probable fault in the control unit.
Lambda probe heater P0141 -
shorted to positive / shorted to negative / open circuit.
Error cause
Shorted to positive: excessive voltage at PIN 35 of the control unit connector.
Shorted to negative: lack of insulation from ground on the sensor connector PIN 4.
The circuit is open: interruption of the circuit.
Troubleshooting
Shorted to positive:
•
Disconnect the control unit connector and the sensor connector.
•
Verify that there is no short to battery positive on sensor connector PIN 3 (corresponding to
control unit connector PIN 31); if there is a short, restore the cabling.
The circuit is open:
•
Disconnect the control unit connector and the sensor connector.
•
Verify continuity of the cabling between the sensor connector and the control unit connector:
Control unit PIN 31 - sensor PIN 3. Restore the cabling if necessary.
•
Verify continuity of the cabling between the sensor connector and the injection relay: sensor
PIN 4 - injection relay PIN 3. Restore the cabling if necessary.
•
If the cabling is intact and the error persists, proceed with the following checks.
Shorted to negative:
•
Disconnect the sensor connector.
