THROTTLE POSITION (TP) SENSOR [SKYACTIV-G 2.5]

Purpose/Function

Detects the throttle valve opening/closing condition, which operates in accordance with the accelerator pedal operation, as basic information for mainly determining the fuel injection amount.

Detects the throttle valve opening/closing condition, which operates in accordance with the accelerator pedal operation, and sends it to the PCM as the throttle valve opening angle signal.

Construction

Built into the throttle body.

A Hall element has been adopted as the detecting element for detecting the throttle valve opening/closing condition.

The TP 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 throttle valve opening/closing, to the PCM.

TP sensor characteristic
