Beschreibung
Zusammenfassung:	A vehicle system (100) includes a conversion catalyst (116), a temperature sensor (156), an indication device (142), and an exhaust gas aftertreatment system controller (132). The conversion catalyst (116) is configured to receive exhaust gas. The temperature sensor (156) is configured to sense a conversion catalyst temperature of the conversion catalyst (116). The indication device (142) is operable between a static state and an impure fuel alarm state. The exhaust gas aftertreatment system controller (132) is configured to receive the conversion catalyst temperature from the temperature sensor (156). The exhaust gas aftertreatment system controller (132) is also configured to compare the conversion catalyst temperature to a conversion catalyst temperature lower threshold. The exhaust gas aftertreatment system controller (132) is also configured to compare the conversion catalyst temperature to a conversion catalyst temperature upper threshold.
