'00 Headaches - Help!

My girlfriend has been having problems with her '00 Cherokee. It has the 4.0 with the automatic and it has around 135,000 miles on it. Within the last year, I have had to replace the Throttle Position Sensor 3 times. It just went bad again the other night. We took it to advanced auto and the guy who read the codes said the Torque Converter Clutch code was on there as well. We went ahead and replaced the Throttle Position Sensor again just to get it drivable. We are now thinking there is something electrical wrong with this thing. It seems like every couple months the TPS goes bad. Any ideas what is wrong?

We've exhausted ourselves working on this thing trying to find the problem. She's to the point now where she is looking at Kia Soul's, which is bad!

Many of the aftermarket sensors for the XJ are junk. They word for a while, and then crap out.

Although they are more expensive, the factory Jeep/Chrysler parts are more reliable. If a dealer is not available, the only other source I would trust would be a NAPA auto parts store. The stuff from the "big box" auto parts places like AutoZone are too hit and miss.

I don't own an XJ any longer, but I still think they are the best of all the Jeep products ever made. My XJ was my favorite vehicle in my 50+ years of driving.
So...I stick around and give advice.

I was also wondering about junk sensors from Advanced Auto. I have heard they are garbage, but I purchased it because of the "Lifetime Replacement". Found out last night when I went in for the 3rd TPS, that the "Lifetime Replacement" only allows two replacements, so I purchased once again another TPS from Advanced. I could understand this from a business standpoint if they had quality parts, but with the reputation of their electronics, I will never know if the Jeep caused them to fail or if they were low quality from the get go.

The reason I am hesitant on buying a TPS from the dealer is because my dealer marks up their parts a good bit, which is fine if it works. But I don't want to pay premium money for a TPS that the Jeep will burn up in a month, and my dealer has no return policy and no warranty.

Cheap parts are cheap for a reason. "Lifetime Warranty" parts are well known to be faulty or out of tolerance right out of the box. I would expect a genuine Jeep TPS to last another 100,000+ miles.

So you don't think it is an electrical problem causing the multiple failed sensors?

If you are buying any sensors that are not genuine Jeep, multiple failures, and short service life does not surprise me at all.

Thanks CJ7-Tim. I knew these were garbage, but had no idea that they were really that bad. I was expecting to get around 50k miles out of one. But instead it seems these wear out before the engine oil!
