ABSTRACT:
A diagnostic system for a vehicle comprises a refueling indicator module and a diagnostic module. The refueling indicator module selectively indicates when a refueling event occurs. The diagnostic module selectively diagnoses a fault in a fuel door position sensor when the fuel door position sensor indicates that a fuel door is in one of an open position for less than a first predetermined period when the refueling event occurs and a closed position for greater than a second predetermined period when the refueling event occurs.
