An assembly for reductant dosing error correction in an exhaust aftertreatment system includes an injector comprising a reductant insertion conduit; a pump configured to advance a quantity of dosed fluid reductant from a reductant source; a reductant source outlet defined by the reductant source and configured to release the quantity of dosed fluid reductant into the reductant insertion conduit; a pressurized reductant receiving chamber defining a pressurized reductant receiver inlet; a reductant insertion pressure sensor; and a doser comprising a controller. The controller of the doser is configured to, based on a first actual pressure of the reductant, calculate a second target flow rate for a second injection event subsequent to a first injection event and control a quantity of dosed fluid reductant released during the second injection event based on the second target flow rate.
