Mazda CX-5 Service & Repair Manual: Throttle Position (TP) Sensor

Mazda CX-5 Service & Repair Manual / Engine / Control / Throttle Position (TP) Sensor

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 inputs 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.

Operation

Inputs the signal, which fluctuates according to the throttle valve opening/closing, to the PCM.
