Barometric Pressure (BARO) Sensor Inspection

NOTE:

Perform the following inspection only when directed.
The following vacuum values are indicated by relative pressure from the PCM. (See PCM REMOVAL/INSTALLATION ).

Connect the M-MDS to the DLC-2.
Turn the ignition switch to the ON position.
Select BARO on the M-MDS.
Verify that the BARO PID (pressure) and barometric pressure are practically equal.
- If not as verified, perform the "Circuit Open/Short Inspection".
  - If there is no open or short circuit, replace the BARO sensor.
- If as verified, go to next step.
