Checking connectors and wiring

Check the connector for the camshaft position (CMP) sensor. Check for contact resistance and oxidation. Check for loose connections. Check for damage carefully.

Check the signal cable between control module terminal #A47 (#A47) and camshaft position (CMP) sensor connector terminal #3. Check for an open-circuit. Check for a short-circuit to supply voltage.

HINT: Use a test lamp with at least a 3 W bulb to determine whether the cable is short-circuited to supply voltage. Check the ground lead between control module terminal #A65 (#A65) and camshaft position (CMP) sensor connector terminal #2. Check for an open-circuit. 

Check the power cable between control module terminal #A29 (#A29) and camshaft position (CMP) sensor connector terminal #1. Check for a short-circuit to ground. Try a new camshaft position (CMP) sensor if no fault is found during the above fault-tracing.

Remedy as necessary.
