Unknown sensor, passenger side of headblock





working on a 2000 cherokee, Il6

Pulled the headblock, and the cord that was plugged into the male end of this black clip broke off, oops

guy at the dealership called it a condenser, it regulated fuel content or something.

the black plastic part has a metal part that comes out and it is fastened to a bolt sticking out of the passenger side of the headblock.

i removed the bolt, its just a bolt with nothing attached.

i still don't know what its real name is, or whether its just some sort of improvised grounding strap.

the wire goes into a wiring harness encased in black tubing

Its called a "Coil Capacitor".

It's wired in parallel with the power wire from the ASD relay to the Coil Rail.

I've seen accounts where it was disconnected and the engine ran fine, but I suggest that you reinstall it properly. The German rocket scientists at Daimler Chrysler put it there for a reason.

Edit: It has nothing to do with fuel.

Sure can't find any mention of it in the 2000 FSM or the wiring diagrams.
Do you have any more information about it?

It's in the 2001 FSM wiring diagrams, and the 2001 parts catalog, part number 56041396AA. The 2000 parts catalog doesn't show it.

Edit:

The 2000 parts catalog lists a coil pack but doesn't show it.


I don't have a 2001 FSM and the 2000 FSM doesn't mention it.

OK, found it in the 2001 XJ parts manual, it's a ignition noise suppression capacitor.
Strange there is no mention of it in the 2000 FSM. Searching XJ sites shows nothing, found it mentioned in WJ and TJ sites for post-2001 models.
Thanks for answering the question.

Thanks for the info guys. I was searching everywhere. Jeep ran fine without it but would like to be on the safe side.

If its an ignition noise suppressor, the engine will run fine without it, and will not be damaged. Its only purpose in life is to try to prevent engine ignition noise from getting in your stereo or a CB. If you're not having noise problems in the audio output of any electronic devices, you don't really need it.
