Well, I fixed the voltage problem by tracing the black wire with the yellow stripe all through the engine. And I got that wire to read 5 to 6 volts everywhere it went, However, now when I plug the wiring harness back into the computer, I get zero volts again!? What could be doing that?

Where's the switch in the hatch? I have a '95. I never seen a switch around there

It's on the latch

That didn't do it, cut the purple wire and they're still on

Hey everyone, this weekend I was driving around town in my 2000 cherokee sport 2wd 4.0L and my jeep started to feel very slugish. I didnt have the acceleration that it normally has and when I was driving down the road and let my foot off the gas it slowed down a lot faster than normal. I pulled over and check all my fluids and eveything was find for the motor oil and the trans oil. The motor never got hot at all either. I just got the jeep about a month ago now and it only has 35k on it. I called the tow truck to prevent any damage and got it towed to a shop where I should be hearing from today but wanted to get your imput on it. Any suggestions to what it is?

Is this about your VSS problem?

OP_Rover

Yes, I was hoping you would know something about it, I saw some of your previous commentary on the VSS.

I don't quite nderstand what you said you were doing in your previous post:

"Well, I fixed the voltage problem by tracing the black wire with the yellow stripe all through the engine. And I got that wire to read 5 to 6 volts everywhere it went, However, now when I plug the wiring harness back into the computer, I get zero volts again!? What could be doing that?"

The "Black wire with a Yellow tracer is actually a Brown/Yellow tracer wire, which is the VSS Sensor Ground, not the 5 volt supply voltage.

What computer are you referring to, the PCM? If so, why did you have the PCM connector unplugged?

Here's a diagram of the VSS circuit and a pinout of the VSS connector.

You can see in this data that the 5 volt supply is from pin cavity 1 of the connector (Violet/Orange tracer wire). The VSS Ground is pin cavity 2 of the connector (Brown/Yellow tracer wire). And the VSS Signal is pin cavity 3 (White/Orange tracer wire).

Hope this helps you understand the VSS circuit.

I fixed the diagram mistake (red ink).

Is there any other commentary on my dome light issue? My jeep is so close to being done, and this is setting it back

Morning everyone. Who would be interested in playing a rousing game of "What is this thing that fell out from underneath my Jeep?"

Context: I have not done any work on my 2001 XJ Classic since I got it back to Nov. 2012. I put in some steering fluid the other day to silence the pump but no screws, bolts or nuts were removed. The next day I heard a nasty noise coming from the front driver side of the engine compartment. I stopped at a stop light, felt something shift then when I stopped in the nearest parking lot this heatshield looking thing fell out from the front driver's wheel well. See the link for picture reference.

Any help would be greatly appreciated!

Look like exhaust heat shield

Are the internals of a front Dana 44 the same as a rear Dana 44? Carrier, R&P, etc

Tire go flat?

+1 that's a piece of heat shielding. Look forward to a warm floor on the passenger side in the near future

93% sure yes as long as they're "standard rotation" High Pinion front axles will have reverse cut gears.

carriers are the same?
