my 08 has a 2 codes po335 and po339 replaced crankshaft position sensor no change, cleared codes and lite came right back on immedietly,2 weeks ago number 1 cylander spark plug blew out of the head replaced with new and new coil,the plug screwed in just like normal and i tried to remove the other three but couldnt loosen them so i just left them alone,what is up with this fit,its having a FIT thanks.

 

Advise for crank patter relearn. I have a GK5 and can confirm my vehicle has this option- not shre about the GDs.

If you got a cheap sensor, advise for warranty for faulty part.
If that doesn't work, advise to check continuity to PCM and outputs.
Could also be out of time.

Good luck.
