INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT WATER TEMPERATURE SENDER GAUGE ASSEMBLY


    1. A01KGMFE01
      Text in Illustration
      *a Slide Rheostat
      *b 35.53 to 35.73 Ω

      Remove the water temperature sender gauge assembly.

    2. Check resistance.


      1. Connect the battery , ammeter, slide rheostat and wire harness, as shown in the illustration.

      2. Adjust the ammeter pointer to indicate "0" using the slide rheostat, then read the rheostat indication.

        Standard
        Temperature °C (°F) Resistance (Ω)
        50 (122.0) 160 - 240
        120 (248.0) 17.1 - 21.2

    NG

    REPLACE WATER TEMPERATURE SENDER GAUGE ASSEMBLY

    OK

  2. CHECK HARNESS AND CONNECTOR


    1. Check open or short of wire harness between combination meter and water temperature sender gauge assembly.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. INSPECT FUEL RECEIVER GAUGE SUB-ASSEMBLY (WATER TEMPERATURE RECEIVER GAUGE)


    1. A01KEGFE01

      Remove the combination meter assembly.

    2. Check resistance of water temperature receiver gauge.


      1. Measure resistance between terminals of the fuel receiver gauge sub-assembly, as shown in the chart.

        Standard: resistance
        Tester connection Standard resistance (Ω)
        A - B Approx. 187 Ω
        A - C Approx. 247 Ω
        B - C Approx. 90 Ω

    NG

    REPLACE FUEL RECEIVER GAUGE SUB-ASSEMBLY

    OK

    REPLACE METER CIRCUIT PLATE
