Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the camshaft position (CMP) actuator solenoid.
  2. Ignition OFF, test for less than 10 ohms between the CMP low control circuit terminal 2 and ground G104.
    • If greater than the specified range, test the CMP low control circuit for an open/high resistance. If the circuit tests normal, replace the PCM.
  3. Disconnect the PCM harness connector X2 at the PCM.
  4. Ignition ON, test for infinite resistance between the CMP low control circuit terminal 2 and ground G104.
    • If less than the specified range, repair the short to ground in the CMP low control circuit.
  5. Engine running, connect the CMP actuator solenoid to B+ and ground with a pair of 10A fused jumper wires. Verify the engine runs rough or stalls.
    • If the engine does not run rough or stall, test or replace the CMP actuator solenoid.
  6. Test the solenoid high control circuit terminal 1 for a short to ground, a short to voltage, or an open/high resistance.
    • If the circuit tests normal, replace the PCM.
