Sensor electrical conformity
Check the cleanliness and condition of the turbocharging pressure sensor and its connections (component
code 1071) and of the engine management computer (component code 120).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the universal bornier to check the insulation and continuity of the following connections:
●3LQ between components 120 and 1071,
●3LP between components 120 and 1071,
●3LN between components 120 and 1071.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the sensor.
If the fault is still present, carry out the following checks:
