APP 1

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 1 should read about 0.35-0.95 volts at idle to above 4.0 volts at wide open throttle.
