DTC LogicINFOID:0000000012431514
DTC DETECTION LOGIC
This diagnosis detects leaks in the EVAP line between f
uel 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 replacemen t. If an incorrect fuel filler cap is used, the
MIL may illuminate.
• If the fuel filler cap is not tighte ned properly, the MIL may illuminate.
• Use only a genuine NISSAN rubber tube as a replacement.

When the vehicle is parked, naturally the fuel level in the fuel tank is stable. It means that output signal of the
fuel level sensor does not change. If ECM senses sloshi ng signal from the sensor, fuel level sensor malfunc-
tion is detected.

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
