P2109 Throttle/Pedal Position Sensor A Minimum Stop Performance

"Sensor A" means that the DTC is referring to a particular sensor, which in this case could be the TPS or the pedal position sensor.

Since it sounds like you have a source for donar parts, I would try swapping the PPS next.

Otherwise, you need to get your hands on wiring diagrams/pinouts for the TPS and the PPS and start checking resistance through them.

Go fast, take chances.
