Camshaft position sensors keep going out?
My rig is a 93 Sport, 4.0L AW4. Basically stock with some minor mods. A few months ago I started experiencing the usual starting issues that the engine would crank over but not start. My OBD I scan tool identified code 54. The camshaft position sensor, which I replaced with a new OEM part from Chrysler along with a new CPS and OEM O2 sensor just to be safe since these 3 sensors work together. I even tested all the wiring, the ECU, fuel pump, relays, fuses, and MAP. All are working fine. Fuel pump is working anf pressure is within spec.
3 days later, I go to start my rid up and it was dejavu. It was turning over, but not starting. Scan tool identifies the same code 54. And befoe you ask, Yes I cleared out the old code.
I replaced the cam position sensor again, jeep starts and runs great, this time for about a month. I drove over to my brothers place to help him with something and when it go to leave, you guessed it. My rig would not start again. Connect the scan tool and surprise, code 54 again.
Something is knocking this sensor out. My rig is currently at a shop that is trying to disciver why these keepgoing out. Has anyone out there had the same problem? If so, what caused your camshaft position sensor to go?
