Various methods are provided for notifying a vehicle operator of various parameters based on an exhaust fluid level sensor of an exhaust fluid storage tank. In one example, the parameter is a consumption rate of the exhaust fluid. In another example, the parameter is an amount of fluid to be added to the exhaust fluid storage tank.

Methods for an exhaust fluid level sensor

A method of supplying fuel vapor to an exhaust aftertreatment device of a motor vehicle is provided. The method includes evaporating fuel on a voltage-biased, resistive heating element, the element set in an enclosure configured to release fuel vapor to the exhaust-aftertreatment device, and indicating that the element is degraded if a current flowing through the element is less than a threshold current. In some embodiments, the threshold current is based on the ambient temperature and/or the amount of fuel in the enclosure.
