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.

TP sensor characteristic

Fail-safe


DTC No.	Fail-safe function
P0122:00	Restricts the upper limit of the engine speed.
P0123:00	Restricts the upper limit of the engine speed.
P0222:00	Restricts the upper limit of the engine speed.
P0223:00	Restricts the upper limit of the engine speed.
P2101:00	Restricts the upper limit of the engine speed. Stops the drive-by-wire control (throttle valve is open at approx. 8° by return spring force).
P2109:00	Restricts the upper limit of the engine speed. Stops the drive-by-wire control (throttle valve is open at approx. 8° by return spring force).
P2135:00	Restricts the upper limit of the engine speed. Stops the drive-by-wire control (throttle valve is open at approx. 8° by return spring force).

Before Service Precaution
WARNING: Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel. Fuel line spills and leakage from the pressurized fuel system are dangerous. Fuel can ignite and cause serious injury or death and damag ...

Generator Control [Skyactiv G 2.0]
Outline Idling stability has been improved by optimum control of generator voltage according to engine operation and electrical load conditions. The PCM determines the engine operation and electrical load conditions based on the input signals from each control part and controls ...

Low Clutch [Fw6 A EL, Fw6 Ax EL]
Purpose/Function The low clutch operates in 1GR, 2GR, 3GR and 4GR and intermittently operates the sun gear by drive force from the turbine shaft. For the low clutch, a centrifugal balance clutch has been adopted to prevent clutch drag and to assure stabilized piston thrust in al ...
