I have a 2005 GMC Envoy w/ inline 6. My MIL light is on throwing codeP0014. I pulled cam actuator solenoid out and cleaned the screens and reinstalled. after about 30-40 miles it came back on. Is there a way to test the solenoid to be certain that is the cause? part is like $50 and all the screens were in tact so I didn't want to replace for no reason....appreciate the help
thanks
