I just finished replacing all my motor mounts and replacing the bad turbo manifold i had....i put everything back together drove it down the road and no trottle responce....no power...alot of supercharger whine which hasnt been normal with the turbo....any ways here are the codes...
p1242

 

A quick search I found this post.. Link

If you are running a Turbo & super charger... This code makes some sense..

Good luck.

 

ended up being a loose hose clamp holding the intercooler....tightened it up cleared codes and problem is gone....thanks guys
