P24C1
EVAP System Leak Detection Pump Switching Valve Performance Stuck Off
Moderate severity
What it means
Same as P24C0 with the valve stuck off. The evaporative system captures fuel vapor from the tank and purges it into intake; leaks or stuck purge valves leak hydrocarbons and cause emissions failures.
Is it safe to drive?

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
