METER / GAUGE SYSTEM Fuel Receiver Gauge Malfunction

DESCRIPTION

• The meter ECU 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 13 Ω with the float at the full position, and 414 Ω with the float at the empty position. The meter outputs battery voltage through two resistors that are mounted inside the meter ECU. The meter ECU measures the voltage between the variable resistor in the fuel sender gauge and the two resistors mounted 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 the battery voltage.

INSPECTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM (FUEL METER OPERATION)

   
   

   1. Connect the Techstream to the DLC3.

   2. Turn the ignition switch to ON.

   3. Turn the Techstream on.

   4. Enter following menus: Body Electrical / Combination Meter / Active Test.

   5. Check the operation by referring to the table below.

      Combination Meter

      Tester Display	Test Part	Control Range	Diagnostic Note
      Fuel Meter Operation	Fuel receiver gauge	Empty, 1/2, Full	-

      OK
      Fuel receiver gauge indication is normal.

   OK

2. READ VALUE USING TECHSTREAM (FUEL INPUT)

   
   

   1. Connect the Techstream to the DLC3.

   2. Turn the ignition switch to ON.

   3. Turn the Techstream on.

   4. Enter following menus: Body Electrical / Combination Meter / Data List.

   5. Check the values by referring to the table below.

      Combination Meter

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      Fuel Input	Fuel input/Min.: 0, Max.: 127.5	Fuel receiver gauge indicates F: 57.0	Unit: Liter
      		Fuel receiver gauge indicates 3/4: 48.3
      		Fuel receiver gauge indicates 1/2: 32.2
      		Fuel receiver gauge indicates 1/4: 16.1
      		Fuel receiver gauge indicates E: 6.4

      Result
      Result Proceed to Fuel level data displayed on the Techstream is almost the same as the fuel receiver gauge indication. A Fuel level data displayed on the Techstream differs from the fuel receiver gauge indication. B

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

   
   

   1. Disconnect the I18 combination meter assembly and N11 fuel sender gauge assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition I18-18 (FR) - N11-2 (FS) Always Below 1 Ω I18-18 (FR) - Body ground Always 10 kΩ or higher I18-17 (FE) - N11-3 (FE) Always Below 1 Ω I18-17 (FE) - Body ground Always 10 kΩ or higher

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

4. INSPECT FUEL SENDER GAUGE ASSEMBLY

   
   

   1. Remove the fuel sender gauge assembly Click here for 2AR-FE, Click here for 2GR-FE).

   2. Inspect the fuel sender gauge assembly Click here for 2AR-FE, Click here for 2GR-FE).

      Result
      Result Proceed to OK A NG (for 2AR-FE) B NG (for 2GR-FE) C
