Signal Too Low

Signal too low

Checking the status




- Start the engine.
Read off the camshaft position (CMP) sensor fault status. Check the status of the fault when the diagnostic status is COMPLETED. If the fault status is "NO FAULT FOUND" when the diagnostic status is COMPLETE there is an intermittent fault.









Continue - Checking connectors and wiring

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

Checking connectors and wiring
Check the connector for the camshaft position (CMP) sensor. Check for contact resistance and oxidation.
Check the signal cable between control module terminal #A27 (#A27) and camshaft position (CMP) sensor connector terminal #2. Check for an open-circuit. Check for a short-circuit to ground.
Check the power cable between control module terminal #A29 (#A29) and camshaft position (CMP) sensor connector terminal #1. Check for an open-circuit.
Try a new camshaft position (CMP) sensor if no fault is found during the above fault-tracing.

Verification




Verification

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




- Reinstall the connectors, components etc.
- Start the engine. Rev the engine to approximately 4000 rpm a few times
- Read off the diagnostic status and the fault status for diagnostic trouble code (DTC) ECM-3010.
Check that the fault status is "NO FAULT FOUND" when the diagnostic status is COMPLETED. If the fault status is "FAULT FOUND" when the diagnostic status is COMPLETED there is a fault.





Is the fault status "NO FAULT FOUND"?

Yes - Verification completed

No - Fault-tracing information

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?

Yes - Exit Fault-Tracing

No - Attempt New Test
