Hey guys I could use help with a code - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

My 15 brz is having an issue with code P2109 on. I have already tried a test throttle body and PCM. Neither fixed the issues. I have tried using my OFT to clear the code and disconnecting the battery. Neither will clear the code out. The engine revs to 1500 rpm and I have no throttle response. Thanks for any help.

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.

Hey there. I tried another pedal with no luck. Any other ideas?
