Mazda CX-5 Service & Repair Manual: Accelerator Pedal Position (App) Sensor

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.

APP sensor characteristic

Fail-safe


DTC No.	Fail-safe function
P2122:00	Regulates the upper limit of the APP sensor output.
P2123:00	Regulates the upper limit of the APP sensor output.
P2127:00	Regulates the upper limit of the APP sensor output.
P2128:00	Regulates the upper limit of the APP sensor output.
P2138:00	Restricts the upper limit of the engine speed. Stops the drive-by-wire control (throttle valve is open at approx. 8° by return spring force).
