BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [LF, L3]

NOTE:
- Perform the following inspection only when directed.
- The following vacuum values are indicated by relative pressure from the PCM. Service and Repair

1. Connect the M-MDS to the DLC-2.

2. Turn the ignition switch to the ON position.

3. Select BARO on the M-MDS.

4. 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 PCM.
