My temp gauge stopped working on my 92 YJ 4.0. Neddle is not moving at all so I'm assuming a broken wire or a bad / disconnected sueding unit. I looked around the block and I don't see anything it may be. Where is the sending unit located and is there a ohm / resistance measurement I can do to diagnose? thanks
snipped-for-privacy@comcast.net did pass the time by typing:
Probably the same as my 93ZJ.
my 89 wrangler sending unit is on the intake manifold, in the back by the fire wall. There is a Purple wire on mine leading to the sending unit. I'm Not sure about the ohm resistence on the yj.
The following is for a cj- With an ohmmeter check the resistance between the post and ground.
73 ohms - Cold Test when engine is slightly warm. A stone cold engine will read a much higher resistance. 36 ohms - Beginning of Band 13 ohms - End of Band 9 ohms - HotMike or someone had posted that CJ one for me. I'd be interested if someone had a list of all the guages and what they should read for the YJ's. Robb 89 YJ
That list is for the 258 engine and is still valid for most of the 4.0 senders too I believe.

Hey Bill, I saw that one before, but I'll be Dam#ed if mine looks like that. Go figure. They probably changed it on my year just to be onrey. I've got the 258 too. Thanks mike for the info on the guages. Lots of help...Thanks all!
