ACCELERATOR PEDAL POSITION (APP) SENSOR [SKYACTIV-G 2.5]

id0140g0007300


Purpose/Function

•  Detects the accelerator pedal depression amount as basic information for mainly determining the fuel injection amount.
•  Detects the accelerator pedal depression amount and sends it to the PCM as an accelerator pedal opening angle signal.

Construction

•  Built into the accelerator pedal.
ac5uun00002916
•  A Hall element has been adopted as the detecting element for detecting the accelerator pedal depression amount.
•  The APP sensor has a main sensor (No.1) and a sub sensor (No.2) for improved detection accuracy.

Operation

•  Sends the signal, which fluctuates according to the accelerator pedal depression amount, to the PCM.
