If no malfunctions are found in the wires and there was voltage between terminals 1 + 3:

Replace Camshaft Position (CMP) sensor:
- Vehicles with engine code AWD, see item 11,
- Vehicles with engine code AWP, AWW, see item 7
Erase DTC memory of Engine Control Module (ECM), see DIAGNOSTIC MODE 4: RESET/ERASE DIAGNOSTIC DATA .
Generate readiness code, see READINESS CODE, GENERATING .

If no malfunctions are found in wires and there was no voltage between terminals 1 + 3:

Replace Engine Control Module (ECM), see REPLACING ENGINE CONTROL MODULE (ECM) .
