My rig is a 93 Sport, 4.0L AW4 it is basically stock. During the summer I thought I had a Crank Position Sensor, CPS issue. My rig would occasionally die for no reason. So I replaced the CPS with a new unit and my rig ran fine up to mid December when it would not start. The engine turned over fine, but would not fire.
After a lot of trouble shooting and testing, the only error code triggered was for the cam position sensor. Upon removing the distributor cap I found that the sensor was pretty dirty and corroded in some places. I pulled the distributor and replaced it with a new unit which includes a new cam position sensor. 2 days later, my rig would not start again. I got the same error code as before. I purchased a new cam position sensor from the dealer and installed it into my original distributor I had just replaced and re-installed my original distributor. I returned the new distributor I purchased and exchanged it for another new one.
My jeep started up and ran fine until last week when it would not start again. I had the same error code again as before. I removed my original distributor I had rebuilt with a new cam position sensor and replaced that distributor with the new one I exchanged. I installed the second new distributor and again it starts and runs fine.
My jeep is now at a shop where they are trying to figure out why I am going through cam sensor. So my question is this. Has anyone out these experienced this same issue with cam position sensors and if so, what was determined to be the cause of why they were failing?
Thanks
