Mazda CX-5 Service & Repair Manual: Barometric Pressure (Baro) Sensor

Mazda CX-5 Service & Repair Manual / Engine / Control / Barometric Pressure (Baro) Sensor

Purpose/Function

Detects the BARO as basic information for mainly determining the fuel injection amount.
Detects the BARO and inputs it to the PCM as a BARO signal.

Construction

Built into the PCM.
A piezoelectric element has been adopted for detecting the BARO.

Operation

Inputs the signal, which fluctuates according to the BARO, to the PCM.
