I'm having a problem with the check engine light coming on in my 2007 gt. It shows the Cam Positioning Sensor (A&B circuit) on both L & R banks, as well as the CPS (intermitted) L&R bank. It only has 11,000 miles on it. I've done the usual mods to it (diablo, c&l racer, under drive pullies, off road x pipe, slp loadmouth, bbk throttle body). I've basically removed all mods one at a time to see if any one thing could be responsable for making the engine light come on. Even with everything removed except for the axel back, it keeps showing the same trouble codes. Is anyone aware of similar problems, or cures. Could the diablo program have had a virus or infected my computor with a dirty program. As soon as i clear the codes it runs great. FYI the check light only comes on when i first start the car up. Please help if you can........ Thanks, D.C.

while all your mods are off put the stock tune in and take it to the dealer.

I planned on doing that. I figured I'd put it out there just in case someone else is experiencing the same problems. Thanks for your reply. D.C.

I have ha problems with cam phasers, sensors, actuators, and what not codes come up but all this was after I put a turbo kit on it. When I clear the codes it runs fine and this is an 07 as well. The only time I get the limp mode or check engine light is when I dont drive it right and backwash my MAF but this doesn't concern you bcause you just have bolt ons
