P0120 code again???

[jdmidwest]

Been good all summer. Fought the code last spring, put in the new sensor, fought it for a few weeks, took it back and put the old one in. Cleaned the MAF sensor and throttle body and have been good all summer.

Today, first cool day, check engine light comes on and P0120 again. What gives.

Prolly need a new TPS if it keeps going out. You can only keep cleaning it for so long.

I replaced the TPS and it run worse. I have since put the old one back and cleaned the MAF sensor and throttle body internally. The TPS does not get dirty, it is just a switch.

Something else is causing the code and the computer is seeing it as a TPS error.
