P20B9 Duramax - Full Repair of DEF Heater

For the Chevy Duramax Diesel, the code P20B9 indicates an issue with the DEF reservoir heater. More often than not, it will be the heater itself that must be replaced, and I show you how to do it. This truck had a P20B9 code in addition to a "Service Exhaust" message. After replacing this heater, I performed a service regeneration of the particulate filter.
