      1. B006OXBN02

        Waveform 1 (Reference):

        Item Condition
        Tester Connection G16-6 (+S), G16-7 (SI) - Body ground
        Tool setting 5 V/DIV., 20 ms./DIV.
        Vehicle condition Engine switch on (IG), wheel being rotated

        Tech Tips

        When the system is functioning normally, one wheel revolution generates 4 pulses. As the vehicle speed increases, the width indicated by (A) in the illustration narrows.

      2. B006MKLE01

        Item Condition
        Tester Connection G16-33 (FR) - Body ground
        Tool setting 5 V/DIV., 20 ms./DIV.
        Vehicle condition Engine switch on (IG), fuel receiver gauge F → E

        Tech Tips

        The height of A is changed on the fuel amount.

        (Fuel receiver gauge F → E [4.2 to 4.6 V → 0.4 to 0.7 V])

      3. B006MT5E02

        Waveform 3 (Reference):

        Item Condition

        Tool setting 5 V/DIV., 20 ms./DIV.
        Vehicle condition Engine switch on (IG), fuel receiver gauge F → E

        Tech Tips

        The height of A is changed on the fuel amount.

        (Fuel receiver gauge F → E [Below 1 V → 4.5 to 9 V])
