Throwing Cam Position Codes. LS2 timing setup
Ok here's my problem. Last year I put in a 408 with LS2 cam position sensor and timing chain. I ordered the extension harness, which was supposed to swap the end wires. It did not so I swapped the pins in the LS2 harness and everything worked great for ~500 miles and 4-5 months until I put the car away for the winter. I double checked the wiring and everything is fine. Check voltage and continuity and it was fine. I checked the cam bolts and also verified that I have the correct cam gear. At this time I performed a cam swap since I am going turbo. Now after the cam swap it still threw code, which I knew it would. I drove the car for a little while and the codes went away (I'm guessing it read that it had x number of normal starts) until the other day when the codes came back. I'm not sure what else to check or do besides getting a new sensor. I don't want to spend $60 bucks on a new sensor if something else could be the problem. The codes P0341 and P0342. Any other ideas before I try a new sensor? It just doesnt make sense to me that it will work and start fine 15-20 times in a row without a backfire, the code will clear, but then come back...

I swapped the two wires on the harness that is on the front of the timing cover. It worked fine all last year and didnt start giving me problems until i took it out of winter storage.

I'll have to try and follow the wires back to the pcm, but I haven't had one problem with starting the car. I thought I would get some backfires or mis starts, but I haven't had any. I did check the cam bolts, which were all still tight and while I had the front cover off I swapped to a more turbo friendly cam and made sure I used loctite on the bolts. Just need to figure out this wiring.
