attached. Refer to 

FL-27, "2WD : Removal and Installation"

 (2WD), 

FL-30, "AWD : Removal and Installa-

tion"

 (AWD).

2. Check if water will drain from the EVAP canister.
Does water drain from the EVAP canister?

YES

>> GO TO 10.

NO

>> Check intermittent incident. Refer to 

GI-45, "Intermittent

Incident"

.

10.

CHECK EVAP CANISTER

Weigh the EVAP canister with the EVAP canister vent control valve and EVAP control system pressure sensor

attached.

The weight should be less than 1.9 kg (4.2 lb).
Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO

>> GO TO 11.

DTC Logic

INFOID:0000000012198503

DTC DETECTION LOGIC

This diagnosis detects leaks in the EVAP line between fuel tank and EVAP canister purge volume control sole-

noid valve, using the negative pressure caused by decrease of fuel temperature in the fuel tank after turning

ignition switch OFF.

If ECM judges there are no leaks, the diagnosis will be OK.

CAUTION:

• Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the

MIL may come on.

• If the fuel filler cap is not tightened properly, the MIL may come on.

• Use only a genuine NISSAN rubber tube as a replacement.
