Barometric Pressure (BARO) Sensor Inspection

NOTE:
  • Because the BARO sensor is integrated in the PCM, replacing the BARO sensor includes replacement of 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 .) (See PCM INSPECTION .)
    • If the measured barometric pressure and the actually measured barometric pressure do not match, replace the PCM. (See PCM REMOVAL/INSTALLATION .)
