WARNING: This page is about a different car, the 2004 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.

Remove EVAP control system pressure sensor with its harness connector connected.
Remove EVAP control system pressure sensor from EVAP canister.
Always replace O-ring with a new one .
Install a vacuum pump to EVAP control system pressure sensor.

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.
