P0455 on Nissan
Evaporative Emission Control System Leak Detected (Gross Leak)
P0455 on Nissan vehicles indicates evaporative emission control system leak detected (gross leak). Au7o has documented this code across 4 Nissan models — most commonly on Frontier, Quest, Rogue. This code means your car's evaporative emission (EVAP) system has detected a large (gross) leak, so fuel vapors that should be sealed inside the fuel and vapor system are escaping into the atmosphere. The EVAP system captures gasoline vapors from the tank and routes them to the engine to be burned instead of polluting the air, and the computer periodically pressure- or vacuum-tests this sealed system. A gross leak almost always points to something obvious and easy, like a loose, missing, or bad gas cap, rather than a deep mechanical failure. It rarely affects how the car drives, but it should be fixed to pass emissions and stop wasting fuel vapor. Typical repair costs on Nissan range from $100 to $1,500, depending on the specific model and root cause.
Common Causes of P0455
- •Loose, missing, or improperly tightened gas cap
- •Worn, cracked, or failed gas cap seal
- •Cracked or disconnected EVAP/vapor hose
- •Damaged or missing fuel filler neck seal
- •Faulty EVAP purge valve stuck open
- •Failed EVAP vent valve
- •Cracked or damaged charcoal canister
P0455 on Nissan by Model
Nissan Frontier(1 issue)
- EVAP Canister and Vent Control Valve Failure Triggering Check Engine Light2000-2004
The evaporative emissions system on these trucks commonly develops faults from a sticking vent control valve, saturated charcoal canister, cracked hoses, or rust/dirt intrusion near the rear-mounted canister. Owners frequently report persistent check-engine lights and failed emissions inspections even though the truck otherwise drives normally. Nissan published EVAP-related service bulletins for leak and vent valve diagnosis on Frontier/Xterra-era trucks.
Nissan Quest(1 issue)
- Rear A/C System Failure2011-2017
The Quest rear A/C system fails prematurely due to the rear evaporator developing leaks. The rear A/C then blows warm air while the front works normally. The rear expansion valve can also stick, preventing proper refrigerant flow. Repairing the rear A/C requires significant disassembly of interior panels.
Nissan Rogue(1 issue)
- EVAP Vent Control Valve / Charcoal Canister Faults Triggering Check Engine Light and Hard Refueling2008-2013
Rogue owners commonly report EVAP system faults caused by a sticking vent control valve, contaminated canister, or related hose issues. The problem often shows up as a persistent check engine light and, in some cases, the gas pump repeatedly clicks off during refueling because the tank cannot vent properly. Nissan service literature for EVAP leak and vent valve diagnosis exists, and complaint/forum activity is consistent across this generation.
Nissan Sentra(1 issue)
- Fuel Filler Neck Corrosion and Rust-Through Triggering EVAP Leaks and Fuel Smell2000-2006
In rust-belt climates, the Sentra's steel fuel filler neck commonly corrodes where road salt and debris collect behind the left rear wheel area. Owners report a strong gasoline odor after fill-ups, visible rust holes, EVAP leak codes, and in some cases fuel dripping during refueling. Nissan issued a recall on certain vehicles for corrosion of the filler tube that could lead to fuel leakage.
