The camshaft sensor monitors the position of the camshaft and reports it to your Jeep Grand Cherokee's computer. When it goes bad, you can experience off-timing. Learn how to replace it here. Show This article applies to the Jeep Grand Cherokee WJ (1999-2004). The camshaft position sensor monitors the position of your camshaft and reports it to your Jeep Grand Cherokee's computer. The computer, along with other components, uses the date from the camshaft position sensor to keep the engine idling. Which means when the sensor is faulty, it gives your Jeep's computer false data, which can result in the timing being off, misfires, and rough idle. The process is not too difficult and it's worth doing at home to save some money on labor. Read on to learn how to replace the camshaft position sensor. Figure 1. Camshaft position sensor.Materials Needed
Step 1 – Disconnect batteryOpen the hood and disconnect the negative battery terminal (black). Wrap it in a towel to avoid it touching anything metal, or it could create a spark. Figure 2.

My 1999 did the same thing and the sensor is in an impossible spot to fix on the bottom of motor above the transmission. I was told that if the vehicle isn't acting up don't fix it. Somewhat of a dummy light. Monday, December 7th, 2020 AT 9:14 AM (Merged) SAM WELLS

Noises
problem My 99 jeep grand cherokee dies if it goes below 1000 rpms and if it goes above 2000 rpm it constantly jerks. Also the oil pressure gauge is not working properly at times it will fluctuate between 20-40 but most times it stays near 0. My ex husband just recently replaced both the ignition coil and the crank shaft sensor unit in the last 3 months. A mechanic friend told me to get in the jeep and turn the ignition key on then off and then on and off and then on and watch for anything to pop up such as the check engine light flashing and count the flashes I did try this but what I got from the dash controls was where the mileage is this appeared "P 0352 P 1391 done" done this mean anything and what is the best thing to do. Also today the trans over temp light came on and the overdrive off light came on. Once I turned the vehicle off for a while and restarted it this went off. Monday, December 7th, 2020 AT 9:31 AM (Merged) P0352 is for the coil being faulty and the P1391 is for the cam and crank sensors being faulty but befor you change them change the spark plugs and wires cap and rotor then try it if it still has probblem then you are looking at changing the sensors and coil Monday, December 7th, 2020 AT 9:31 AM (Merged) What are the symptoms of a faulty camshaft sensor?A glowing check engine light, stalling, poor acceleration and bad fuel mileage are all possible signs your camshaft position sensor may be failing. Gone are the days of carburetors and distributors, replaced by a variety of sensors that help a car's computer get the maximum performance out of the engine.
