Hey guys I was driving on the highway today and my cel came on and I got these two codes p0335 and p0336. My truck is pretty much stock with a afe stg2 and a straight pipe. Are these anything to worry about? I heard it's normal with a chip like the TST but I don't have any performance chip or programmer! Why is his occuring? I hate seeing the CEL on!

Thanks

 

Could be a bad sensor........I've also just have mine get dirty and in need of cleaning and then sealing.

 

Where is the sensor located? I just see if it came unplugged

 

Drivers side of the lower block.......I doubt it came "unplugged" as it is held in place with two locking mechanisms.

 

Ok thanks I'll check... If it's dirty I'll clean it. But if that doesn't work I'll take it to a *********** and have it replaced

 

Thanks guys figured it out... Cleaned it and now no codes... This site is awesome.

 

Great...........I have sealed my connection with silicon, and it had stopped the codes.
