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.
  1. Connect the M-MDS to the DLC-2.
  2. Switch the ignition ON (engine off).
  3. Measure the barometric pressure using a barometer.
  4. 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 .)
