Nissan Rogue P0455
TL;DR
P0455 is a large EVAP leak. On the Nissan Rogue the usual culprits are a loose or worn gas cap, a cracked EVAP hose or purge line, or a failing purge/vent valve. Low severity, safe to drive.
Why P0455 shows up on the Nissan Rogue
The Rogue's EVAP system captures gasoline vapors from the tank and routes them through a charcoal canister into the engine to be burned. When the computer runs a leak test and finds a large drop in system pressure, it sets P0455. Because the Rogue sees a lot of stop-and-go family driving and frequent refueling, the single most common trigger is simply a gas cap that was not tightened until it clicked, or one whose rubber seal has hardened with age.
Model-typical causes and rough likelihoods
- Loose, cross-threaded or worn gas cap (~40%) — the cheapest and most frequent cause; check this first.
- Cracked or disconnected EVAP hose / purge line (~25%) — rubber lines near the canister and fuel tank get brittle with heat and age.
- Failing EVAP purge valve or vent control valve (~20%) — commonly reported as the Rogue gets older; a stuck-open valve mimics a large leak.
- Charcoal canister or filler-neck fault (~15%) — less common but worth checking if simpler parts test fine.
Owner tips
Before spending money, remove the gas cap, inspect the seal, reinstall it until it clicks several times, then clear the code and drive a few days. If it returns, a shop can run an EVAP smoke test to pinpoint the leak quickly rather than replacing parts by guesswork. Avoid overfilling the tank at the pump, since topping off can saturate the canister and trip EVAP codes on the Rogue.

Frequently asked questions
Is it safe to drive my Nissan Rogue with a P0455 code?
Yes. P0455 is a low-severity emissions code on the Nissan Rogue that does not affect engine performance, safety, or drivability. The car will run and drive normally. You should still repair it soon so the check-engine light turns off and the vehicle passes an emissions or inspection test, but there is no risk in continuing to drive in the meantime.
What is the most common cause of P0455 on a Nissan Rogue?
The most common cause of P0455 on a Nissan Rogue is a loose, cross-threaded, or worn gas cap that no longer seals the fuel system. Other frequent causes include a cracked EVAP hose or purge line and a stuck-open purge or vent valve. Because the gas cap is the cheapest and most likely culprit, it should always be checked and re-tightened first.
How much does it cost to fix P0455 on a Nissan Rogue?
If the cause is the gas cap, a replacement runs about 15 to 40 USD and you can install it yourself. If a hose, purge valve, or vent valve is at fault, expect roughly 120 to 350 USD including parts and labor. A shop diagnostic with an EVAP smoke test typically adds 75 to 150 USD but pinpoints the leak and prevents replacing good parts.
