hi,with all 3 codes this tells me that there may be a problem with the wiring or a component, you will need to check the circuits of each of the app sensors,there will be a 5 volt supply to each of these app sensors,
ACCELERATOR PEDAL POSITION (APP) SENSOR The accelerator pedal assembly contains 2 individual APP sensors within the assembly. The APP sensors 1 and 2 are potentiometer type sensors, each with the following circuits:
The APP sensors are used to determine the pedal angle. The control module provides each APP sensor a 5-volt reference circuit and a low reference circuit. The APP sensors then provide the control module with signal voltage proportional to pedal movement. Both APP sensor signal voltages are low at rest position and increase as the pedal is applied.
