Zusammenfassung:An automotive resistance type water temperature fuel sampling system belongs to the technical field of automobile application. The automotive resistance type water temperature fuel sampling system settles a problem of low measurement precision in the prior-art water temperature fuel sampling system. According to the automotive resistance type water temperature fuel sampling system, an electric signal output end of an instrument power supply is connected with resistors R1, R3 and R4; the resistor R1 is connected with the resistor R2 and the resistor R5; the resistor R2 is grounded; the resistor R2 is connected with a capacitor C1; after the capacitor C1 is connected with the resistor R5, the capacitor C1 is connected with a first AD sampling port AD0 of a signal sampling device; the resistor R3 is simultaneously connected with a resistor R6 and a fuel sensor; after the resistor R6 is connected with a capacitor C2, the resistor R6 is connected with a second AD sampling port AD1 of the signal sampling device; th
