Abstract
The present invention provides a method of compensating for an erroring sensor in a flexible fuel compensation control system for a flexible fueled vehicle. The methodology provides a method for identifying preselected operating conditions without the output of the erroring sensor. As such, the flexible fuel compensation control system may still be employed to ensure vehicle drivability even in the absence of input from an erroring sensor.
