Engine was overheating last week, I replaced the thermostat and all was well until today.


First the "Reduced Engine Power" warning displayed, and I could feel the reduced power as if a cylinder or two weren't firing. Shortly after the "Service Traction System" warning showed.


I recieved 3 separate engine fault codes: P1125, P2125, and P2138. All point to the Accelerator Pedal Position sensor.


So my question is, where is the APP sensor located, and is it likely that anything else is going on?
