EVAP Control System Pressure Sensor
- Remove EVAP control system pressure sensor with its harness connector connected 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. See Figure and Figure.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.
