Hello, my name is Bobby. Thank you for the question. Can you tell me why you replaced the TPS? Was there a code for it? What codes did you have in the computer?

Thank you. When you get this series of codes the issue is typically in the accelerator pedal assembly or in the throttle body motor itself. Most of the time it is the pedal assembly. I would first make sure that the throttle body does not have any loose terminals and also check the wiring going to the pedal assembly. Pay close attention to any of the wiring under the kick panel under the far left side under the dash. It is common to have corrosion issues there. If those are fine then you would either need to test or replace the pedal assembly to start.
