1997 TJ camshaft sensor: myth or fact?

I think I need to replace the camshaft position sensor in my '97 TJ. I have been searching for the part and can't find it to save my life! My Haynes manual says that it was in the 2000, but fails to mention the '97. Did the '97 come with a camshaft sensor? I recently replaced the crankshaft sensor and that didn't solve all the issues. Any input from the think tank that is Jeep Forum would be greatly appreciated!

Yep, pull the distributor cap off & you'll find the sensor underneath that thin round plastic protective cover below the rotor.

Alright; thats what I thought. How much of a hassle is that sucker to replace?

Typically?

1) Remove distributor
2) Disassemble distributor (requires removal of a roll pin through the drive gear, then the shaft pulls out from the top. Suggest you make witness marks on the gear and shaft - it should not matter whether you get the gear 180* around, but why take chances?)
3) Remove/replace sensor
4) Reassemble distributor (Clean shaft. Make sure shaft bore is clean. Drop shaft through housing. Replace gear. Align witness marks made in (2). Replace roll pin.)
5) Replace distributor, making sure proper timing is retained.

Easier said than done - but the last time I had to change a CMP (on RENIX,) it took me about two hours. Then again, I've done plenty of distributors before, and I've been doing this sort of thing for a while...

Changing a CPS is a piece of cake on a 4.0 distributor TJ.Maybe 15 minutes?
