So I've been working for the last 4 month of My Cobalt SS/SC and giving the codes P0340,P0341 and P0017. I took to a knew tuner because the timing was right on the car, since I followed to manuals instruction. The tuner tells me today that scanner says that the car is of time by 3 on the exhaust cam. And the car si on time, what could it be? The car has cop caps stage 1

 

Did you install the cams yourself? If not, I'd take it back to whoever did, or physically check

 

The cams where already installed on the car when I purchase the car. We think it could be dm the cam sensor out of space

 

p0017 is cam crank correlation and that will be thrown for an engine that is out of time and possibly a bad sensor a cam sensor housing out of time will not cause a p0017
