hey all.Check engine light coming on with P0012 intake A camshaft position timing over retarded Bank 1 . From the research I have done on the internet it seems to be the cam position sensor. Any thoughts on if I am correct or not before I go buy the parts? I have a 2002 S60 non turbo 2.4L which I service at the dealer faithfully. Just don't have the cash right now to take it to them so got a friend to do the readout after the check engine light came on.Thanks for your help!
