Barometric Pressure (BARO) Sensor Inspection: Notes
WARNING: This page is about a different car, the 2004 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- Perform the following inspection only when directed.
- The following vacuum values are indicated by relative pressure from the BARO sensor.
- Connect the WDS or equivalent to the DLC-2.
- Turn the ignition switch to ON.
- Select BARO on the WDS or equivalent.
- 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.
- If not as verified, perform the CIRCUIT OPEN/SHORT INSPECTION .
- Apply vacuum of -25.0 kPa {-187 mug, -7.38 inch}
to the BARO sensor, and verify that the BARO variation from that of Step 4 is approx. 25.0 kPa {187 mug, 7.38 inHg}.
- If not as verified, perform the CIRCUIT OPEN/SHORT INSPECTION .
- If there is no open or short circuit, replace the BARO sensor.
- If not as verified, perform the CIRCUIT OPEN/SHORT INSPECTION .
