Solving P0455 on Your 2019 Nissan Rogue
A P0455 on your 2019 Rogue means the ECM detected a large EVAP leak. Your T32-generation Rogue with the 2.5L engine is out of Nissan's basic warranty but within the federal emissions warranty. Start with the gas cap.
Symptoms
- Check engine light with P0455
- Faint fuel odor near the rear
- Gas cap seal worn after 6+ years
- Failed emissions test
Causes by Probability
- Gas Cap Seal (Very High Likelihood): Worn rubber seal. Replace for $10–$25.
- Vent Control Valve (Medium Likelihood): Nissan's vent valve sticking. $120–$220.
- Purge Volume Control Valve (Medium Likelihood): PVCV stuck open. $100–$200.
- Vapor Line (Low Likelihood): Deteriorating rubber hose. $80–$200.
- Charcoal Canister (Low Likelihood): Saturated from overfilling. $200–$350.
Diagnostic Steps
Replace the gas cap ($10–$25), clear the code, drive 2–3 cycles. If P0455 returns, a smoke test will locate the leak. The vent control valve is near the charcoal canister under the rear of the Rogue.
Warranty Coverage
Nissan's basic warranty has expired. The federal emissions warranty (8yr/80k) covers EVAP through 2027. Check mileage with your dealer.
Safe to Drive?
Yes. P0455 doesn't affect the Rogue's 2.5L engine, CVT, or AWD.
