Code P20BF Ford Description

The reductant heater and sender assembly contain a pickup tube for the reductant pump modules, an electric heating element, a reductant temperature sensor, and an electrode type level sensor. The heating element is directly above the pickup tubes inlet filter. When the reductant temperature sensor detects the diesel exhaust fluid temperature dropping to the freezing point of 12°F (-11°C), the Powertrain Control Module (PCM) will command the glow plug control module to provide voltage to the heating element. The heating element thaws liquid reductant within the reductant heater and sender assembly reservoir during cold ambient temperatures.
