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.
