Fault-Tracing

Fault tracing DEM-P093215

Checking the connectors and leads








- Ignition off
- Check the connector between the Differential Electronic Module (DEM) and the oil pressure sensor with respect to contact resistance and oxidation.
- Check connector A with respect to depressed or damaged pins, contact resistance and oxidation.
- Start the engine and read the value of the oil pressure sensor signal in order to check the function.

Hint: The oil pressure should be 0.8 MPa when the engine is idling. The oil pressure sensor has a measurement range from 0 to 4 MPa.

Remedy as necessary.

Other information:
- Signal specification
- Temperature / pressure sensor active on demand coupling (AOC), replacing
- Differential electronic module (DEM), replacement

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reinstall the connectors, components etc.
- Engine running.
Read off the oil pressure.

Hint: The oil pressure should be 0.8 MPa when the engine is idling. The oil pressure sensor has a measurement range from 0 to 4 MPa.





Is the oil pressure OK?

Yes - Troubleshooting procedure complete

No - Fault-tracing information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?
