摘要: A method for isolating an actual sensor bias in a fuel delivery system having a fuel pump includes monitoring first, second and third fuel pump parameters, detecting first and second fuel pump sensor biases based on the monitored first, second and third fuel pump parameters, modeling a fourth fuel pump modeled parameter based on the monitored second and third fuel pump parameters, and isolating the actual sensor bias in one of the detected first and second fuel pump biases based on the monitored third fuel pump parameter and the modeled fourth fuel pump modeled parameter.
