97 Tahoe camshaft sensor replacement relearn - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I had a couple of hesitations and P0340 code this past week. I swapped out the cam shaft position sensor. When I started it after the swap, it ran rough. What is the process for the relearn?

Can I do this without a highend scan tool?

Thanks,
Steve

Did you remove your distributor?

Yep, and that was my problem. When I dropped it back in, I was a tooth or two off. It looked good at the time. The cam retard was +/- 45 when I tried to start it. We got in into the mid 20's and then moved it a tooth or two. Then we got the cam retard to 0. Ran perfect after that. The P1345 popped up in there at some point.

The reason I asked about the relearn, I saw that message when ordering the part that it may be possible.

Thanks for the reply Speedy.
