We replaced our TPS Sensor in our 2003 Dodge Durango but now when you start it, it idles real high and when you are driving it will burst to 2 on the RPM and then at stops it will sometimes die. Is there something that we maybe did wrong? We unpluged the negative on the battery, took off the old TPS and put on the new one. Wasnt hard or done wrong. How do I get it to idle right now? I figured that even if the old TPS wasnt bad then it wouldnt hurt the truck to put a new one on. Why is it worse now?

 

Could be a faulty TPS, they aren't necessarily good right out of the box. Another thing that jumps out at me is the IAC or Idle Air Control valve. Easy to fix. It's on the back of the throttle body. The best thing would be to take the throttle body completely off clean it an replac it with a new gasket. There is a thread about it in the Do It Yourself sticky at the top of the 1st gen Durango section

 

+1 i agree with mike. Try a new tps, clean the throttle body and iac, install new gasket, reset the pcm, and see if the prob comes back.

 

The IAC was replaced at Tires Plus. I tried to tell them I heard the TPS Sensor needed replaced because of how it was acting but they didnt change it. I talked to Oreilys where I bought the TPS Sensor and one person said he had to drive his vehicle for a while to get it to run right. I am just so scared to drive it and get stranded somewhere. I am never trying to fix a car on my own again.

 

heres a troubleshooting step, i assume you did NOT throw away the old sensor yet, simply put it back on, if the problem goes away the you got a bad sensor (seems very likely to me) and you did nothing wrong, a little hiccup like this is no reason to swear off doing your own work on the car.

 

Also you might want to reset the PCM after replacing the TPS or any electrical operating system for the motor or trans.

If you don't reset the setting automatically starts in the last known positions until it re-learns the parameters. Also it could be a faulty sensor. Reset first then replace.

 

Yes -- I purchased one from RockAuto and it was faulty out of the box. I went with the Airtex/Wells part but replaced it with a BWD model and the BWD worked fine.

 

You never know if you get a faulty sensor...unless you test it but whos gonna test a sensor you just bought?

 

We just ended up taking the truck to this new mechanic we were told about. It wouldnt go more than 20 mph when I was driving there but luckily it isnt far. He said the sensor needed a code. I was able to return the sensor we bought and was not charged much for him to put in the other one. The truck is running great now. No idle problems at all.

 

Nice. Good thing you got her running great now!
