Tracking Down P0455 on Your 2022 Ford Escape
A P0455 on your 2022 Ford Escape means the system found a large EVAP leak. Your 4th-generation Escape on the C2 platform may still be within Ford's basic warranty. The gas cap is the most common and cheapest fix.
What You May Notice
- Check engine light with P0455
- Faint fuel smell

Causes by Likelihood
- Gas Cap Seal (Very High Likelihood): Loose or worn. $10–$25 OEM replacement.

Diagnostic Steps
Tighten the gas cap and drive 2–3 days. FORScan reads Ford-specific data. For professional diagnosis, a Ford dealer uses FDRS and smoke testing.
Warranty Status
Ford's basic warranty (3yr/36k) runs through 2025. The federal emissions warranty (8yr/80k) covers EVAP through 2030.
Safe to Drive?
Yes. P0455 doesn't affect the Escape's 1.5T or 2.0T engine, transmission, or AWD.
