SYSTEM AND METHOD FOR INDUCING FUEL SYSTEM FAULT

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. 种根据本公开原理的系统包括故障命令模块、燃料控制模块以及故障检测模块。故障命令模块基于用户输入选择性地产生引起燃料系统故障的命令。燃料控制模块响应于引起燃料系统故障的命令，将燃料校正系数自动调节到第预定范围之外的目标值。燃料控制模块基于燃料校正系数致动与发动机的汽缸相关的燃料喷射器。当燃料校正系数在第预定范围之外时，故障检测模块检测燃料系统故障。
