Barometric Pressure Sensor: Testing and Inspection

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.

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.
