ACCELERATOR PEDAL
The Accelerator pedal module (APM) is mounted in place of accelerator pedal and is connected to the ECU
by wires. The APM is a potentiometer whose output voltage changes according to the pedal position. ECU
applies a reference voltage to the APM sensor and then measures the voltage that is present on the APM
sensor signal circuit. The ECU uses the APM sensor signal for further calculation of fuelling & other engine
operational parameters.
