EVAP Control System Pressure Sensor
- Remove EVAP control system pressure sensor with its harness connector connected.
- Remove EVAP control system pressure sensor from EVAP canister. Do not reuse the O-ring, replace it with a new one.
- Install a vacuum pump to EVAP control system pressure sensor.
- Turn ignition switch ON and check output voltage between ECM terminal 32 and ground under the following conditions.
SPECIFIED CONDITIONS
| Applied vacuum kPa (mmHg, inHg) |
Voltage V |
| Not applied |
1.8 - 4.8 |
| -26.7 (-200, -7.87) |
2.1 to 2.5V lower than above value |
CAUTION:
- Always calibrate the vacuum pump gauge when using it.
- Do not apply below -93.3 kPa (-700 mmHg, -27.56 inHg) or pressure over 101.3 kPa (760 mmHg, 29.92 inHg).
- If NG, replace EVAP control system pressure sensor.
