I looked around for some decent pictures or instructions on replacing the Crank Sensor on my 1997 ZJ but could not find any so i decided to make my own.
I found using this many extensions made it much easier to be able to turn the ratchet as the trans shifter is in the way, about 10 more inches would have been perfect though. The Crank Sensor bolt size is 11mm. I used a swivel extension on the end and it worked perfectly.
The long bolt is for pushing the sensor from the plug over the trans housing onto the other side.
This photo is taken from laying under the vehicle feet out the passenger side just in front of the cross member that holds the trans up.
The shift cable is sitting right on top of the CPS so i found the best place for it was being pulled slightly down below the Crank Sensor so i could pull it up once it was unbolted.
A little better idea of where it is.
For the sake of the picture i moved the shift cable to the side but the Crank Sensor pigtail would prevent any upward movement of it from here so pull the shift cable down toward you.
It was pretty stuck in here, i had to twist and pull upwards to be able to get it loose but it came out.
The spark plug wire you see is Cyl #6 looking down from the passenger side behind the motor. The Crank Sensor wire is the small one coming out from behind the block going into the large connector just under my hand.
Unplug your old one and plug the new one in. Push it on top of the bell housing over to the other side. I had to use a long rod/bolt to get it across as the new wire was stiff from being wound up in the box.
Getting the new Crank Sensor in was oddly much harder than getting the old one out. I had to angle it in just the right way so that it would slide into the hole and not be too tall and hit the body.
I had to thread the bolt on with just the socket on because the angle was just too odd.
Tighten it up. I read around that the proper torque is 60 InLbs but i didnt have a torque wrench on my so i just guessed =)
If there is anything i left out please let me know =)
