Reductant Purge Control Valve B Stuck Closed. P24E0 indicates that the powertrain control module (PCM) has detected a fault in the reductant purge control valve B circuit, specifically that the valve is stuck closed. The PCM commands the valve to open during a purge event but sees no expected change in pressure, flow, or reductant level, so it sets this code.
