Mazda CX-5 Service & Repair Manual / Engine / Control / Accelerator Pedal Position (App) Sensor

Purpose/Function

Detects the accelerator pedal depression amount as basic information for mainly determining the throttle valve opening.
Detects the accelerator pedal depression amount and inputs it to the PCM as an accelerator pedal opening angle signal.

Construction

Built into the accelerator pedal.
A hall element has been adopted as the detecting element for detecting the accelerator pedal depression amount.

Operation

Inputs the signal, which fluctuates according to the throttle valve opening/closing, to the PCM.
