PID/DATA Monitor Inspection
WARNING: This page is about a different car, the 2020 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- The BARO sensor is built into the PCM. When replacing the BARO sensor, replace the PCM.
- Connect the M-MDS to the DLC-2.
- Switch the ignition ON (engine off).
- Measure the barometric pressure using a barometer.
- Verify that the measured barometric pressure and the actually measured barometric pressure (PID: BARO) input from the BARO sensor match. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0)]
.) (See PCM INSPECTION .)
- If the measured barometric pressure and the actually measured barometric pressure do not match, replace the PCM. (See PCM REMOVAL/INSTALLATION .)
