COMPONENT PARTS

Accelerator Pedal Position Sensor

INFOID:0000000009266954

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 potentiometer which transform the accelerator pedal

position into output voltage, and emit 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.
