That is not classified as a TPS code. In fact there is no such thing as a TPS code , it does not exist.
Are there codes associated with the throttle body and accelerator position pedal sensors, yes. There are many scenarios I have seen with component problems. Simply reading a code and replacing a part is ignorant, time consuming and expensive.

This thread has turned into one that is 99% inaccurate.

I had one go out (code P2138) and it would go into Limp mode at the most in opportune time (like accelerating onto the interstate).

A brand new pedal assembly was like 75 bucks from the dealership, and it was 3 screws and about 5 min to replace.

Is this a thing? I'm asking because mine went bad and I did indeed have that throttle controller on it.
