Accelerator Pedal Position Sensor

INFOID:0000000009758327

The accelerator pedal position sensor is installed on the upper end

of the accelerator pedal assembly. The sensor detects the accelera-

tor position and sends a signal to the ECM.

Accelerator pedal position sensor has two sensors. These sensors

are a kind of potentiometers which transform the accelerator pedal

position into output voltage, and emit the voltage signal to the ECM.

In addition, these sensors detect the opening and closing speed of

the accelerator pedal and feed the voltage signals to the ECM. The

ECM judges the current opening angle of the accelerator pedal from

these signals and controls the throttle control motor based on these

signals.

Idle position of the accelerator pedal is determined by the ECM

receiving the signal from the accelerator pedal position sensor. The

ECM uses this signal for the engine operation such as fuel cut.
