I have a 2004 Dodge Diesel. I replaced the Throttle Position

Customer Question

I have a 2004 Dodge Diesel. I replaced the Throttle Position Sensor because that was what the check engine code indicated. $350 later it still will run and then act like a switch flips and goes into limp mode.

Hello and welcome to JustAnswer!
If you're setting an accelerator pedal positions sensor code possible causes would be the sensor itself, wiring and connections, or the engine controller. ECM issues on these are very rare, if you replaced the sensor with a known good part and it's still setting a code then you almost certainly have a wiring issue.
What P codes are currently setting?

It was a p2121 and a p2127 and we even replaced the tps that is under the battery box on the drivers side

That's the cruise control servo.
Do you have the part numbers for any parts replaced?
