Abstract
A control system for diagnosing a fuel system of a vehicle is provided. The system generally includes a correction term module that estimates a fuel correction term based on a first fuel correction value and a second fuel correction value, wherein the first fuel correction value is based on a first period and the second fuel correction value is based on a second period, and wherein the first period is longer than the second period. A diagnostic module diagnoses the fuel system of the vehicle based on the fuel correction term.
