Abstract: A method for monitoring an SCR injection system is disclosed. The method includes operating a pump, and measuring a first pressure drop value in the SCR injection system during actuation of a reductant injector. A second pressure drop value in the SCR injection system is measured during a further actuation of the reductant injector. It is determined to perform a deposit mitigation strategy based on the first pressure drop value and the second pressure drop value.
