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