Faulty Signal or Signal Missing

Faulty signal or signal missing

Checking the status




- Start the engine.
Check whether the fault is permanent or intermittent. Read off the fault status from the camshaft position (CMP) sensor. When the camshaft position (CMP) sensor is tested, "Diagnostic ready" must be displayed.
The fault is permanent if the fault status is "Fault found". The fault is intermittent if the fault status is "No fault detected".










Continue - Checking the component and wiring

-------------------------------------------------

Checking the component and wiring
- Check the connector for the camshaft position (CMP) sensor. Check for contact resistance and oxidation.
Check that the camshaft position (CMP) sensor is correctly installed. Check that neither the camshaft position (CMP) sensor nor the housing is damaged. Damage may affect the position of the sensor in relation to the camshaft rotor.

Hint: This diagnostic trouble code (DTC) may be caused by a faulty camshaft position (CMP) sensor.

Remedy as necessary.

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




- Reinstall the connectors, components etc.
- Start the engine.
Check the fault status of the camshaft position (CMP) sensor when the sensor is tested. When the camshaft position (CMP) sensor is tested "Diagnostic ready" must be displayed and the fault status must be "No fault detected".





Is the fault status "No fault detected"?

Yes - VERIFIED

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?

Yes - Exit Fault-Tracing
