P24F7Exhaust Aftertreatment Fuel Air Purge Valve Stuck Closed
The aftertreatment HC dosing or reductant purge valve is stuck closed. The ECM commands purge but the line is not cleared, leaving residual fluid that can foul nozzles or freeze in cold weather. Subsequent dosing events also fail because backpressure does not match the model.
