2016 Pete 389 throttle position sensor

You can ck the hinge on pedal that can wear out but may if it doesn't move much, just need cleaning up, and the new tps you can buy from Ebay, screwed on the cleaned up pedal should save you big bucks?

 

Cummins? Sure could be the sensor, but due to the intermittent nature it could very well be a wiring rub all the same.

Thorough inspection of the wiring from the pedal to the engine ECM at all metal contact points. Inside and outside the cab. The wiring will be 2 separate groups of 3 wires that are twisted. Green, purple and blue. The ladder brackets or wiring supports on the LR of the engine are hot spots for issues. But I have also found rubs inside.

Pretty sure the TPS is available separate thru Williams controls. I will dig for it on Monday and see about a number.

VIN?

 

The newer dual sensor hall effect style TPS are pretty durable. Most issues I have had with them is wires rubbed in engine bay.

 

The sensor is not available separately on your pedal.

 

Good morning I hope this is allowed trying to figure out how to use this forum. I recently had my isx3 rebuilt and since the rebuild I have had this pedal problem as well except mine is so bad the engine light comes on then the stop engine light comes on and then she pretty much just idles on the side of the road going about 10 miles an hour. I was lucky enough to be able to change the sensor and the wiring I'm just wondering if they did something with my wiring under the hood that has created this problem I can run for about a day with no issue and then from there on out it's downhill. I have cleaned out my pedal the codes that it threw were total PT hours zero total fuel hours zero primary level fuel and sensor open. Any help would be greatly appreciated
