    INSPECT UREA PUMP


    1. Inspect the level sensor.


      1. A003FVME01

        Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        14(LV1) - 6(ELV1) Float position is upper 53.56 to 56.08 kΩ
        Float position is lower 1.40 to 1.46 kΩ
        Table 1. Text in Illustration
        *a

        Component without harness connected

        (Urea Pump)
        *b Upper
        *c Lower

    2. Inspect the tank heater.
