Code P208B Ford Description
When the vehicle is shut down, PCM closes injector and actuates reductant purge valve, causing the pump to reverse flow and bleed down pressure on reductant pressure line. The PCM then opens injector to allow gas to enter reductant pressure line, which in turn allows the pump to purge all remaining DEF from the system and return it to reductant tank. The PCM closes injector and returns purge valve to forward position. The PCM commands glow plug control module to provide voltage to reductant pump assembly internal heating element when reductant temperature approaches 12°F (-11°C).
