Abstract
A system and method for determining whether a vehicle is equipped with an ORVR system. A processor receives a signal from a fuel pump or the like indicating the fuel being dispensed by the fuel dispenser. The processor is programmed to determine a threshold vapor concentration level based on the signal. Processor further receives a signal from at least one environmental sensor indicating at least one environmental condition to which the fueling operation is exposed. The processor is further programmed to adjust the threshold vapor concentration either up or down dependent upon the environmental condition. Finally, processor receives an actual vapor concentration from a vapor sensor. The processor then compares the actual vapor concentration value with the adjusted threshold vapor concentration value to determine whether the vehicle is equipped with an ORVR system.
