METER / GAUGE SYSTEM Fuel Receiver Gauge Malfunction

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 4 Ω with the float at the full position, and 110 Ω with the float at the empty position. The meter outputs battery voltage through two 220 Ω resistors that are mounted in parallel inside the meter CPU. 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

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM

   
   

   1. Check if a CAN communication DTC is output Click here.

      Result
      Result Proceed to CAN communication DTC is not output. A CAN communication DTC is output. B

2. PERFORM ACTIVE TEST USING INTELLIGENT TESTER

   
   

   1. Connect the intelligent tester to the DLC3.

   2. Ignition switch on (IG).

   3. Turn the tester 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
      Needle indication is normal.

   
   

   NG

   REPLACE COMBINATION METER ASSEMBLY Click here

   OK

3. READ VALUE USING INTELLIGENT TESTER

   
   

   1. Connect the intelligent tester to the DLC3.

   2. Ignition switch on (IG).

   3. Turn the tester 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 signal Min.: 0, Max.: 127.5	Fuel gauge indicates (E): 7.5 (L) Fuel gauge indicates (1/2): 35.0 (L) Fuel gauge indicates (F): 62.9 (L)	-

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

   
   

   NG

   REPLACE COMBINATION METER ASSEMBLY Click here

   OK

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

   
   

   1. 

      Disconnect the E1 and fuel sender gauge assembly connectors.

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

      Standard resistance
      Tester Connection Condition Specified Condition E1-34 (FR) - 2 Always Below 1 Ω E1-19 (FE) - 1 Always Below 1 Ω 2 - Body ground Always 10 kΩ or higher E1-34 (FR) - Body ground Always 10 kΩ or higher

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

5. INSPECT FUEL SENDER GAUGE ASSEMBLY

   
   

   1. 

      Disconnect the fuel sender gauge connector.

   2. Measure the resistance between terminals 1 and 2 of the connector according to the value(s) in the table below.

      Standard resistance
      Float Level Resistance (Ω) F 3.0 to 5.0 Between E and F 3.0 to 4.0 (Gradually changes) E 109.0 to 111.0

   3. Remove the fuel sender gauge assembly Click here.

   4. Check that the float moves smoothly between F and E.

   5. Check if the fuel sender gauge arm is deformed.

   
   

   NG

   REPLACE FUEL SENDER GAUGE ASSEMBLY Click here

   OK

6. REPLACE COMBINATION METER ASSEMBLY

   
   

   1. Replace the combination meter assembly with a new one or a normal one Click here.

      OK
      The operation of the combination meter assembly returns to normal.

   
   

   NG

   REPLACE ECM Click here

   OK
