ACCELERATOR PEDAL POSITION (APP) SENSOR [SKYACTIV-G 2.0]

id0140f4007300

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.

am3zzn00003386

• 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.
