DTC DETECTION LOGIC

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 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.
