Abstract
A system according to the principles of the present disclosure includes a fault command module, a fuel control module, and a fault detection module. The fault command module selectively generates a command to induce a fuel system fault based on a user input. The fuel control module automatically adjusts a fuel correction factor to a target value outside of a first predetermined range in response to the command to induce a fuel system fault. The fuel control module actuates a fuel injector associated with a cylinder of an engine based on the fuel correction factor. The fault detection module detects a fuel system fault when the fuel correction factor is outside of the first predetermined range.
