Solving P0455 on Your 2024 Nissan Frontier
A P0455 on your 2024 Frontier means the ECM detected a large EVAP leak. Your D41-generation Frontier with the 3.8L V6 is fully under warranty. The gas cap is the most common cause—check it before scheduling a dealer visit.
Symptoms
- Check engine light with P0455
- Possible faint fuel smell
- Gas cap not clicking
- EVAP monitor incomplete
Most Likely Causes
- Gas Cap (Very High Likelihood): Loose or not seated. Tighten until it clicks.
- Software Calibration (Medium Likelihood): ECM may need a Nissan TSB update.
- Vent Control Valve (Medium Likelihood): Factory defect. Warranty replacement.
- Purge Volume Control Valve (Low Likelihood): PVCV stuck open. Warranty-covered.
- EVAP Line Fitment (Low Likelihood): Assembly issue. Warranty-covered.
What to Do
Tighten the gas cap and drive 2–3 days. If P0455 persists, visit a Nissan dealer for free diagnostics and repair under warranty.
