  • System and method for monitoring location of diesel exhaust fluid in a dosing system
    Patent number: 11873751
    Abstract: A system including a pump fluidly connected to a fluid reservoir, the pump configured to direct diesel exhaust fluid (DEF) from the fluid reservoir to an injector fluidly connected to the pump via a flow line. The system also includes a first pressure sensor configured to determine fluid pressure at a first location in the flow line between the pump and the injector and a second pressure sensor configured to determine fluid pressure at a second location in the flow line between the pump and the injector. The system further includes an air source coupled to the injector via an air flow line, the air source configured to direct air to the injector via the air flow line and a controller communicatively coupled to the first pressure sensor, the second pressure sensor, and the air source, the controller configured to diagnose the system.
