Very - very intermittently my daughter had the Jeep stall for no reason on her. I've driven it may times w/o an problems. I knew the catalytic converter was bad so I went and replace it this morning - thinking maybe it was the problem. My Jeep also needed the Ox sensor that mounts to the cat..
When they were finished the mechanic tried to start the car and no luck. It turned over but wouldn't fire. This never happened to us. From his 10min. diagnostic with a scanner he thought it was most likely a crankshaft position sensor since the scanner wasn't picking up a speed. By chance he cleared the codes (even though none were being shown) and the car started right up.
We have only had the Jeep for about 8-months but with this problem I decided to give it plugs, rotor, cap, plugs, and crank position sensor. I saved the sensor for last and glad I did.
The sensor is at about the 11 o'clock position on the bell housing. I could just barely snake my arm in there with the right wrench combo and remove the bolt. First thing - the sensor doesn't come out easily. It seems to be stuck - I didn't want to pry too hard because of the second problem. Second - there doesn't seem to be enough room to get the sensor out. There is only about 1" until the sensor will hit the cowling and the sensor is about 2" long.
Any tricks? 1) to provide more space for removal. 2) to loosen the old one for removal. 3) or a trick on how to do this.
