DESCRIPTION

The meter CPU uses the fuel sender gauge assembly to determine the level of the fuel in the fuel tank.

The resistance of the fuel sender gauge will vary between approximately 15 Ω with the float at the full position, and 410 Ω with the float at the empty position. The meter outputs battery voltage through two 820 Ω resistors that are mounted in parallel inside the meter ECU. The meter CPU measures the voltage between the variable resistor in the fuel sender gauge and the two resistors mounted in parallel in the meter. Voltage measured at this point will vary as the float of the fuel sender gauge is moved. The highest voltage observed should be approximately half of battery voltage.

INSPECTION PROCEDURE

1 PERFORM ACTIVE TEST BY INTELLIGENT TESTER

  1. Connect the intelligent tester to the DLC3.
  2. Turn the ignition switch to the ON position.
  3. Turn the tester ON.
  4. Enter following menus: DIAGNOSIS / OBD/MOBD / METER / ACTIVE TEST.
  5. Check the operation by referring to the values in the table below.

OK: Needle indication is normal.

2 READ VALUE OF INTELLIGENT TESTER

  1. Connect the intelligent tester to the DLC3.
  2. Turn the ignition switch to the ON position.
  3. Turn the tester ON.
  4. Enter following menus: DIAGNOSIS / OBD/MOBD / METER / DATA LIST.
  5. Check the values by referring to the values in the table below

OK: Fuel value signal displayed on the tester is almost the same as needle indication

3 INSPECT FUEL SENDER GAUGE ASSEMBLY

INSPECT FUEL SENDER GAUGE ASSEMBLY
  1. Disconnect the connector from the fuel sender gauge.
  2. Check the the float moves smoothly between F and E.
  3. Measure the resistance between terminals 1 and 2 of the connector according to the value(s) in the table below.

Standard resistance: Fuel sender gauge

Standard resistance: Fuel sender gauge

4 CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SENDER GAUGE ASSEMBLY)

CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SENDER GAUGE ASSEMBLY)
  1. Disconnect the F20 and C10 connectors.
  2. Measure the resistance according to the value(s) in the table below.
