P20c7 Chevrolet Description

The reductant heater and sender assembly contains pickup tube for reductant pump module, an electric heating element, a reductant temperature sensor and an electrode type level sensor. The heating element is directly above pickup tubes inlet filter. When 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 heating element. The heating element thaws liquid reductant within reductant heater and sender assembly reservoir during cold ambient temperatures.
