Anyone know anything about Trucks. I took my truck to Autozone after my check engine light came on, and it came up that my Cam Shaft Position sensor was bad. So my truck has two, I replaced one, and started it turned it on and the light went off, then I took it for a drive and it was fine, but I went to turn around and it quit on me. Then the check engine light came back on, so I switched the one I took out with the other old one, and tried it again thinking only one was bad. And it did the same thing, so are both my sensors bad or is their another problem?
