Hello and welcome to JustAnswer!

P0120 is for the accelerator pedal position sensor, which is part of the accelerator pedal assembly. This is a circuit code and indicates an issue with the sensor itself, wiring or connections. I see you mentioned checking the sensor's signal, but if it was checked and found to be ok then the problem wasn't currently happening. The only time testing can be done is when the code is active. Wiring and connection problems are possibly but odds are the sensor itself is failing.
