Could be the issue, but more commonly the crank position sensor fails. The cam sensor is a hall effect sensor located under the distributor rotor. It just pulls off. The crank sensor is bolted to the backside of the engine on the drivers side through a hole in the bellhousing. I believe they are 11mm bolt heads.

anybody????
i went to auto zone and they said my truck doesnt have a camshaft position sensor.
i am wondering if the magnet has fallen off of mine, and where it would be in the distributer, and will i have to pull the distributer to find it.
i purchased a crankshaft position sensor, but i doubt if this is my problem, but mine had burnt wires from the manifold. i repaired the wires, but was still backfiring, so i'll install new one tomorrow.

I had better luck finding a camshaft position sensor when calling what it is a Hall effect sensor, otherwise I was also told it didn't have a cam sensor even though I was holding in my hand...

If it is backfiring into the intake then either your ignition timing or cam timing iss off, which the crank or cam sensor could cause that problem.

Take off the distributor cap with the two screws. Take off the rotor. The Cam Sensor is what is left. A black flat thing. Pull strait up on it and it will come out. If the magnet fell off it would be in the bottom of the distributor. it's on the bottom and has no place it could go. Try calling it a pickup, or pickup coil to the geeks at Autozone.
