2007 S CEL P000A Cam Sensor Slow to Respond. Replaced Sensor. Light Still comes On In the First Block after a Cold Start But Runs Fine. Timing Chain was Replaced a few Months ago and thats when The Light Issues Started.
Dealer say they don't see any codes But I pull it up With My Scanner.
Milage Went From 24 to 29.5 after I replace The original Sensor, so I know we fixed something. but still the Light Comes On.
Any Help Out There.
Already Bald No Hair Left to Pull Out.

 

Did you ever figure out what this was? I am currently getting both this code as well as P0012 Cam timing retarded.
