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.
