ACCELERATOR PEDAL POSITION (APP) SENSOR [SKYACTIV-D 2.2]

id0140z7007300

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 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.

• The APP sensor has a main sensor (No.1) and a sub sensor (No.2) for improved detection accuracy.

Operation

• Inputs the signal, which fluctuates according to the accelerator pedal opening/closing, to the PCM.
