QuestionQUESTION: We have been trying to go through the troubleshooting and replacing sensors, checking wires and spacers all that stuff. We are finally at wits end and may have to take the van in to the dealer so they can charge us more than we care to spend. P0016 is the code, we replaced the two sensors for cam and crank. After replacement we noticed it worked for a little bit then the light came back on and the jerking motion is back. We checked the wires and come to find: the middle wire in the plug of the cam sensor is not lighting our test light whereas the other two are. We have a blue (no current), blue/gray(current) and a pink/yellow(current. The blue has no current to show the light on our test light. Can this problem be traced to the pcm and possibly be a short, or do you think it is the Transmission Flexplate/Tone Ring? If the short is the cause we have traced from the plug to about five feet toward the pcm and tested for current. Have not had the light come on and the wiring goes through a whole bunch of mumbo jumbo to get to the pcm. We don't want to continue testing the wire if it is not supposed to have a current or if there is a better place to look, because we would have to unravel many feet of wire harness and tape. Sorry for my aggravation and thanks for reading, any suggestions?

QUESTION: There are three wires, Blue, Blue/gray and pink/yellow. The blue that is the middle wire on the plug has no current.
Answerok the cam sensor signal wire
disconnect the pcm connectors and disconnect the cam sensor
get an ohm meter check for resistance to ground with both disconnected U want the ohm meter to show OL or no resistance if U show some then u have that wire touching ground or another wire else where in the harness to the pcm. If that is good then do an ohm test from the pcm connector to the cam sensor same wire color if u get ohms resistance then U have a bad pcm.
