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. Verify that the BARO sensor output value (PID: BARO) is within the specification. (See ON-BOARD DIAGNOSTIC TEST ). (See PCM INSPECTION ).
