P24F6Exhaust Aftertreatment Fuel Air Purge Valve Stuck Open

Q: ¿Qué significa el código P24F6?

Exhaust Aftertreatment Fuel Air Purge Valve Stuck Open. On systems that inject HC dosing fuel or AIR-assisted reductant into the aftertreatment, a purge valve clears the line after each dosing event. The ECM detects the valve stuck open — pressure or flow does not build up against a closed valve, so the dosing line cannot be charged. Common on diesel HC-doser hardware (DPF regen support).
