Abstract
A system includes a first heater positioned in or proximate to an exhaust aftertreatment system in exhaust gas-receiving communication with an engine, a second heater positioned downstream of the first heater, and a controller coupled to the first and second heaters. The controller is structured to activate the second heater in response to determining that a compound deposit is likely present.
