- The following vacuum values are indicated by relative pressure from the PCM.

1. Connect the WDS or equivalent to the DLC-2.
2. Turn the ignition switch to the ON position.
3. Select BARO on the WDS or equivalent.
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 BARO sensor.
