1. Test the resistance of the intake Cam Position (CMP) actuator solenoid. It should be 8-12 ohms. Compare to the exhaust solenoid--should be the same.

2. Check the harness for opens, grounds, and shorts to voltage.

3. Check for loose terminals at the Powertrain Control Module (PCM) and solenoid.

Both of those solenoids are right there on top of your valve cover, there not real expensive if you just want to replace them honestly 9 out of 10 times that is what is wrong. It is important to remember that for this system to work you have to have full clean oil if your low on oil or dirty fix that first. And as for the running your right it is hard to notice at an idle you could have rough idle, yes you can fix this and yes you need to.

Expert:  Reggie Whiddon replied 4 months ago.

Pull both solenoids, check the resistance with a voltmeter, if that checks take a couple of jumper wires and operate the solenoid with 12 volts you should feel it click and you should see the valve move if not replace that sucker clear your code and beat your chest. I will wait to hear back from you look forward to helping you

Hi Reggie,sorry for the delay in responding,went to chrysler carlisle just got back. Appreciate your expertise on the problem with the sky. Will try what you suggest this coming weekend. I do have a daily driver to use in the mean time. What will happen if the car is driven in the condition it's in? Just curious>Will let you know what I find after testing and replacing. Do you know where I can find a shop manual for this car? Haven't been able to locate one.---------------Rick
Expert:  Reggie Whiddon replied 4 months ago.

That is a good question, your local parts stores have haynes manuals which are usually pretty good. I can provide you alot of information as needed. And as far as driving it honestly you can drive it for a little but it is something you need to fix. If you get to bogged down in the diagnostic just get the solenoids and replace them, they are 9 times out of 10 the problem. So it will be next weekend before you check it?

Customer: replied 4 months ago.
Thnx for the response. Yes probably be next weekend before I can get to it. Very busy working around here and at job .Have to work by priority you know. Have other daily driver In the mean time. Tried advance,autozone,and napa,manual not availiable according to them tried the internet but haven't found anything yet.Thought you might have a lead on one? Only get on here once or twice a week reason for slow response time
