Hello thanks for letting me post here..I am a Mechanic in Australia and have brought a 2017 Honda HRV..Car is going into limp mode no throttle response.The code is P2122.I have changed the Throttle body and the accelerator pedal but no joy. Would anyone here know where the accelerator pedal Relay is located or would anyone have a wiring diagram for this car ..Thanks in Advance ....Is this a common problem?
