Mazda CX-5 Service & Repair Manual: Manifold Absolute Pressure (Map) Sensor

Mazda CX-5 Service & Repair Manual / Engine / Intake / Manifold Absolute Pressure (Map) Sensor

Purpose/Function

Detects the intake air pressure introduced into the cylinder as basic information for mainly determining the fuel injection amount.
Detects the intake air pressure introduced into the cylinder and inputs it to the PCM as an intake air pressure signal.

Construction

Installed on the intake manifold.
A sealant diaphragm has been adopted as the detecting element for detecting the intake air pressure.
IAT sensor No.2 is integrated.

Operation

Inputs the signal, which fluctuates according to the intake air pressure, to the PCM.
