awhile ago my jeep started running really funny, it would shift at really high rpms and idle either super low or super high. So i hooked up a code reader and it said i had a bad TPS sensor so i replaced it and everything was fine for a month or two till i didn't drive the jeep for about a week and when i came back it was doing the same thing again. so i pulled out the code reader and the same code came up. so i once again replaced the sensor. ran fine. next day did the same thing again pulled the same code and everything. this will be the third sensor i have replaced. what am i doing wrong? Could it be something else?

 

From what I have read, and come to understand, is that you should only buy this part at the dealership, because all of the auto stores sell ones that have a very high failure rate. So my question is, did you buy a cheap one? Lol

 

Make sure the ground for the tps is good. This could also be a cause for so many not to work right

 

i just went to checker and bought what they had i dunno it wasn't cheap but i get discounts for where i work. it had i life time warranty so i have only paid for one technically but this whole going through a sensor every week or so is getting really old

 

Yeah, they have a lifetime warranty for that reason... I would say, first make sure the ground is good. If so, go get one from the dealership...

 

i guess ill start my checking the ground when i get off work tonight and go from there...

 

Lifetime warranty from those stores generally means you're gonna keep replacing those parts for your lifetime.

 

Possibilities include a poor quality sensor or a bad connector for that sensor. When I replace a sensor, I always perform a comprehensive inspection of all of the contacts, then give it a thorough spray of electrical contact cleaner, add a dab of dielectric grease and reconnect.

As a side note, always best to post the exact code number(s) as most circuits have multiple codes that can be set with OBD
