Things You'll Need
New crankshaft position sensor
Socket set with extensions
Wrench set

Instructions
1
Locate the crankshaft position sensor on the driver side of the bell housing, about half way down. It is secured with two 7/16-inch bolts and has a cable that runs up and onto the engine.

2
Remove the two 7/16-inch bolts from the bracket holding the CPS. A socket with extension or an open end wrench can be used, depending on what works best for you.

3
Move up the cable about 6 to 8 inches and you will find a clip that holds the cable against the bell housing of the Jeep. Remove the cable from the clip.

4
Trace the cable from the CPS to the the top of the engine and locate the weather-proof connector where it plugs into the main wiring harness. Unplug the connector, being careful not to break the tab on the connector.

5
Remove the old CPS and cable from the Jeep. Install the new CPS in the location that you removed the old one from, using the two 7/16-inch bolts. Route the cable from the new CPS up to the clip on the bell housing and install the cable under it.

6
Route the remaining cable up through the engine compartment and plug in the weather-proof connector. The connector should only go in one way and it should click in when properly seated.
