The engine light came on while out of town and the code is P0122 TPS/Pedal Position sensor A circuit low input. Doed anybody have any ideas or advice as to how to fix this problem or what to check for. Thanks

 

Throttle Position sensor i didnt have much luck foolin mine. Does it idle rough and run wierd at high rpms? I ran mine 300 miles home but had to stop off and shut the pickup off and it helped sometimes. Also you might try draining your computer by disconnecting both terminals on the batteries and touching the negative and pos together on both sides. This will reset your ecm. And mine costed i think about 175 when i got home. Hope this helps

 

Thanks. I stayed over a few days until I could get it into a diesel shop. This old guy working there laughed and curced all these new computers. Blew some compressed air into the connection at the firewall cleared my code charged me 75.00 for the reading and it runs fine. Go figure a 75.00 blast of air. Thanks again for your help.

 

Keep me posted on how your trucks doing.

I just had the same problem (worse symtom's) and I had to change the sensor. List is $504.
