Code U010E 2016 GMC Sierra Description

The U010E diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates that there is a communication problem between the Engine Control Module (ECM) and the Reductant Sensor Module (RSM). The Reductant Sensor Module is responsible for monitoring the levels of diesel exhaust fluid (DEF) in the selective catalytic reduction (SCR) system. This system is crucial for reducing harmful emissions by converting nitrogen oxides into harmless nitrogen and water vapor.
