Thanks for the information. I unplugged the cam sensor and started the vehicle, I seen no difference in behavior with or without it plugged in. Am going to check the key on volts at the harness, from reading the service manual, says it should be 1 volt, if less then you have a short. Do you think its necessary to unplug the pcm to perform this test?
