Component Testing

1. Measure the resistance of each CMP actuator solenoid valve assembly. Resistance should be between 8-12 ohms.
2. Connect a jumper wire between the CMP actuator low reference circuit at the solenoid and a good ground. Connect a fused jumper wire to the CMP actuator high control circuit at the solenoid. Momentarily touch the fused jumper to B+. Observe the spool valve inside the CMP actuator. The spool valve should move from fully closed to fully opened position.

The pontiac G5 has a defect on some of them that need a new ignition switch. I just had to get mine replaced because mine did the exact same thing. If you remove the fuse it will not fix the problem!
