HI,
Is there a way to test the cam position sensors and actuators before stripping things down to replace chain? My car has been stored a while, only has 48k miles, and there's no noise at start up. Getting only code P0008.

Thankd

I'm sure this is possible with appropriate scanner (i.e., a Tech II) or with knowledge of the electrical characteristics. However, for those of us who don't have these, we can always resort to old school methods. Personally, I have found many faulty connections in cars >5 years, let alone cars that are nearly 15 years old. I would start by pulling the connector from all cam and crank sensors, applying dielectric grease to the contacts, reinstalling, and then clearing codes. This will ensure that the signal to the ecm is not impeded.


Assuming the code returns, the p0008 can result from several other issues, including intermittent sensors. Hard to tell though, based on a description alone. It may be worth exploring the suggestions provided here, about halfway down the page: https://www.google.com/amp/s/www.troublecodes.net/pcodes/p0008/?amp

If you would please fill out your profile information, I would not have to look up your previous posts to find out that your car is an 07 with 3.6 engine. Yes, a TechII can command advance of each of the 4 actuators in 5 degree increments to a total of 20 or 25 degrees IIRC. If you profile (generally) where you live, someone who lives nearby may volunteer to connect their TechII. Good Luck
