Circuit Description
The ECM supplies a 5 or 2.5 volt reference signal and a ground to the APP sensor 1 or 2. The ECM calculates on
these signal lines. The APP sensor output changes as the accelerator pedal is moved. The output of the APP 1
and APP 2 sensor are low, about 0.4 ~ 0.7 volts and 0.2 ~ 0.35 volts respectively at the closed throttle position.
As pushing the accelerator pedal, the output increases so that the output voltages will be about 4.3 ~ 4.8 volts
and 2.1 ~ 2.4 volts individually when accelerating fully with the kick down, at Wide Open Throttle (WOT).
