Abstract
Various methods and systems are provided for health assessments of a fuel system. In one example, a method for an inlet metering valve (IMV) includes reducing electrical driving of the IMV, monitoring a response time of the IMV in real-time responsive to the reducing, and determining if the IMV is degraded based on a response of IMV current over a duration, the duration beginning after an initial decrease in current caused by the reducing.
