• Also check wires for short circuit to each other.

  Specified value: INFINITY Ω

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

• Replace Camshaft Position (CMP) Sensor -G40-. See item  2.
• 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) .
