Abstract
A dosing control system for a vehicle includes a pump control module and an enabling/disabling module. The pump control module controls a pump that provides dosing agent to a dosing agent injector located upstream of a selective catalytic reduction (SCR) catalyst in an exhaust system. The enabling/disabling module disables the pump for a predetermined melting period after engine startup when the dosing agent is frozen and selectively activates the pump during the predetermined melting period to cool the dosing agent injector when a tip temperature of the dosing agent injector is greater than a predetermined temperature.
