P2122 Accelerator pedal position (APP) sensor 1 circuit low voltage

P2127 Accelerator pedal position (APP) Sensor 2 circuit low voltage

P2138 Accelerator pedal position (APP) sensor 1-2 correlation

With these code condition that is set the engine will be in a reduce power mode, the fix is to replace the APP sensor, regardless , if the problem persist, this would be the ECM
