The measured oil pressure signal is below the normal operating range (< 0,1 V).

Possible causes are:

The oil pressure sensor wiring is defective. (Shorted to ground.)

The oil pressure sensor power supply is not correct.

The oil pressure sensor is defective.

 

Reaction in EEM

The FC is stored and the oil pressure warning lamp is activated. Engine power will be reduced (Degradation Level 1). The CAN message indicates active fault. The engine protection functions that depend on oil pressure are not active.

NOTE: The engine oil pressure protection is not active. The engine may be damaged, if the oil pressure is too low.

 

Solution

First save the error log and then erase it. Restart the ECU after erasing the error log. If the fault occurs again during the next driving cycle, check the following paths:

Check the oil pressure sensor wiring, the connectors and the contact surfaces of the connector pins (possible oxidation).

Check the 5 V power supply to the sensor.

Check the operation with another oil pressure sensor to see if the oil pressure sensor is defective.
