DTC P0455 EVAP CONTROL SYSTEM
On Board Diagnosis 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.
DTC Confirmation Procedure
CAUTION:
Never remove fuel filler cap during the DTC Confirmation Procedure.
