APP 2

RANGE 0-5 VOLTS:
The PCM uses the APP sensors to control fuel delivery as requested by the driver. Three APP sensors are located in a module at the base of the accelerator pedal. The PCM only requires information from one sensor, the other two serve as fail safes. APP 2 should read approximately 4.5 volts at idle and should steadily decrease to approximately 1.0 volt at wide open throttle.
