Note
1. Connect the SSTs
(WDS or equivalent) to the DLC-2.
2. Turn the ignition switch to ON.
3. Select BARO on the SSTs
(WDS or equivalent).
4. Verify that the BARO PID (pressure) and barometric pressure are practically equal.
- If there is no open or short circuit, replace the barometric pressure sensor.
5. Apply vacuum of -25.0 kPa {-187 mmHg, -7.38 inHg}
to the barometric pressure sensor, and verify that the BARO variation from that of Step 4 is approx. 25.0 kPa {187 mmHg, 7.38 inHg}.
- If there is no open or short circuit, replace the barometric pressure sensor.
Circuit Open/Short Inspection
1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION.)
2. Inspect the following wiring harness for open or short. (Continuity check)
Open circuit
- Barometric pressure sensor terminal A (harness-side) and PCM terminal 1G
- Barometric pressure sensor terminal B (harness-side) and PCM terminal 2H
- Barometric pressure sensor terminal C (harness-side) and PCM terminal 2K
Short circuit
- Barometric pressure sensor terminal C (harness-side) and power supply.
- Barometric pressure sensor terminal C (harness-side) and body GND.
- Barometric pressure sensor terminal A (harness-side) and power supply.
- Barometric pressure sensor terminal A (harness-side) and body GND
