Hello,

I have a 1989 Cherokee 2.5 Auto. Recently the throttle position sensor has gone bad, and I can't find a replacement. Scouring the internet and local dealerships has yielded nothing, all I've learned is that the part is discontinued and even the sites that say they have it don't. I don't have a mechanical bone in my body. Does anyone know where this could be found? There was a reference to it being custom available in a post from 2010, but alas no link.

The Jeep is in great condition otherwise, less than 70k miles. Retiring it is not an option, but I don't know what to do. Any guidance would be greatly appreciated. The part number in question is 33004649.

 

Rockauto.com has them in stock.

 

autozone shows a listing...http://www.autozone.com/autozone/par..._131814_0_3498

 

So sadly both of those are for the manual transmission model only. At a total loss here...

 

Check to see if the one from the dodge dakota is the same I know that they used the same 2.5 in the dakota as the xj.But I don't know if it was all the same sensors, but worth a shot.

 

Yes, but the Dakota used a Chrysler trans while the Jeep used the AW4.

2.5 autos were indeed rare.

 

Cruiser, wasn't there a post a while back when a guy dismantled and cleaned his tps? Isn't it a simple slide pot? (or two?)
Also Preacher, you DO know they are adjustable?

 

Not that I remember.
They flat wear out inside.

How has it been determined that the TPS is bad? Symptoms?

according to the bottom of this page, the manual and auto use the same sensor:

Yep^ That's what it says. All the same on Gas 2.5, 87-90. Whodthunkit?



Also I found that other post I had mentioned ;

Since mine was on the fritz I figured what have I got to loose. Took a putty knife and a hammer and it split apart at the seams. Cleaned it out, gave it a layer of dielectric grease and epoxied it back together. Been driving a week now with no issues. Granted it might quit tomorrow but for now its fine.

Now I understand the ole saying that necessity if the mother of invention. Actually fixed one of my power lock actuators the same way.

 

look again click on the pic two different one number 11 for stick no15 for autohttp://www.factorychryslerparts.com/...roduct=4356014

 

#15 is for both auto and manual 87-90, it says. #11 is for the 86, Z7X-716 engine. And I thought I was too poor to pay attention!

 

well that makes their application listing useless and misleading

 

automatic has a in and out connector to tell tranny what to do manuals have one as forz7x engine its still 2.5 hes talked to these guy still not finding one
