Ls1 to LS2 swap...camshaft position sensor code

[Scott1225]

Did a swap and used the Katech harness to adapt the sensor. It is now throwing the P0343 code. This is a new sensor, so I pretty sure that isn't it. The car is now real erratic with starting...sometimes it doesn't at all...other times, it fires right off. It has something to do with the timing. At about 3k, it pulls ALOT of timing out. It will have a total of 7-9* at times.


Is there something in the PCM that needs to be changed for the LS2? Bad sensor?

Thanks

Pin's A & C at the cam sensor end may need to be swapped. I have seen this on more than one occasion.

Huge thanks on that...fixed the car

No problem. BTDT many times already.

is there anything else needed going from an ls1 to an ls2 (fbody).

If you use the LS2's intake, you will need a MAP extension harness as the MAP is up in the front instead of the back of the manifold.

Possibly the only good thing about the LS2 intake.
