Investigating P0455 on Your 2024 Ford Escape
A P0455 on your 2024 Ford Escape means the PCM detected a large EVAP system leak. Your 4th-generation Escape on the C2 platform is under full warranty. Check the gas cap first—it's the simplest and most common cause.
Symptoms
- Check engine light with P0455
- Possible faint fuel odor
- Gas cap not clicking
- EVAP readiness monitor incomplete
Top Causes
