Here it is I was having a P0340 and P0341. I bought two brand new sensors because I have had an issue like this for awhile now and it would go away but come back a month or so later . Anyway I put two brand new sensors on a Cam and a Crank truck wouldnt start at all so I put an old sensor in the cam position sensors spot and my truck started up fine no codes at all for a week . now im getting the these codes again and im about over it. I checked wires and plugs everything looks good there. Any help would be greatly appreciated . The dealer wont take back electrical items but I guess I can just tell them the cam sensor wont work.
