Checking components and connections
Check the connector for the camshaft position (CMP) sensor. Check for contact resistance and oxidation.
Check the signal cable between engine control module (ECM) terminal #A47 (#A47) and camshaft position (CMP) sensor 2. Check for an open-circuit. Check for a short-circuit to supply voltage. Check for a short-circuit to ground.
Check the power supply cable between control module terminal #A57 (#A57) and camshaft position (CMP) sensor 1. Check for an open-circuit. Check for a short-circuit to supply voltage. Check for a short-circuit to ground.
Check the ground lead between control module terminal #A65 (#A65) and camshaft position (CMP) sensor 3. Check for an open-circuit.
Remedy as necessary.
