4. If NG, replace EVAP control system pressure sensor.
DRAIN FILTER
1. Check visually for insect nests in the drain filter air inlet.
2. Check visually for cracks or flaws in the appearance.
3. Check visually for cracks or flaws in the hose.
4. Blow air into port A and check that it flows freely out of port B.
5. Block port B.
6. Blow air into port A and check that there is no leakage.

INFOID:0000000009481453
This diagnosis detects a very large leak (fuel filler cap fell off etc.) in EVAP system between the fuel tank and
EVAP canister purge volume control solenoid valve.
CAUTION:
• Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the
MIL may illuminate.
• If the fuel filler cap is not tightened properly, the MIL may illuminate.
• Use only a genuine NISSAN rubber tube as a replacement.
