Note
1. Connect the SSTs
(WDS or equivalent) to the DLC-2.
2. Turn the ignition switch to ON (Engine OFF).
3. Select MAP PID on the SSTs
(WDS or equivalent).
4. Verify that the MAP PID (pressure) and barometric pressure are practically equal.
- If there is no open or short circuit, replace the MAP sensor.
5. Apply vacuum of -25.0 kPa {-187 mmHg, -7.38 inHg}
to the MAP sensor, and verify that the MAP 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
- MAP sensor terminal A (harness-side) and PCM terminal 2H
- MAP sensor terminal D (harness-side) and PCM terminal 1J
- MAP sensor terminal C (harness-side) and PCM terminal 2K
Short circuit
- MAP sensor terminal C (harness-side) and power supply.
- MAP sensor terminal C (harness-side) and body GND.
- MAP sensor terminal D (harness-side) and power supply.
- MAP sensor terminal D (harness-side) and body GND
