What does a reductant tank heater do for diesel?
Simply put, the reductant tank heater refers to the heater that keeps the DEF or reductant warm when temperatures are below freezing. The reductant, which is a reducing agent, helps reduce oxides of nitrogen (NOx) within the diesel exhaust after treatment system. Common Reductant Tank Heater Issues
What is the reductant heater control system used for?
The reductant heater control system is used by the Powertrain Control Module (PCM) to heat up the Diesel Exhaust Fluid (DEF) to prevent it from freezing.
What is the code for a Duramax reductant tank heater?
By using a code reader the most common code is P20B9, DEF reservoir heater control open circuit/low voltage. The most common repair for the P20B9 code is either replacing or manually engaging the reductant tank heater.
What does DTC stand for on reductant heater?
Diagnostic trouble code (DTC) P20BA stands for “Reductant Heater “A” Control Circuit Performance.” This trouble code sets when the powertrain control module (PCM) has detected that the voltage signal from the control circuit of the designated reductant heater “A” is out of the expected range.
