ACCELERATOR PEDAL POSITION (APP) SENSOR [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]
SM2565324
id0140u0007300
Purpose
• Detects the accelerator pedal depression amount as basic information for mainly determining the throttle valve opening.
Function
• Detects the accelerator pedal depression amount and sends it to the PCM as an accelerator pedal position signal.
• For the accelerator pedal position signal, main (No.1) and sub (No.2) signals of different characteristics have been adopted to enhance detection accuracy.

Detection principle
-
• When current flows to the energizing coil from the IC, the receiving coil generates voltage which causes electromagnetic induction between the energizing coil, the rotor coil and the receiving coil.• When the rotor coil positional relationship changes, the generated voltage changes.
Operation
1.The TP sensor detects (1) the accelerator pedal depression amount.
2.The TP sensor sends (2) the detected accelerator pedal depression amount to the PCM as accelerator pedal position main (No.1) and sub (No.2) signals.
