Fuel Receiver Gauge Malfunction

WIRING DIAGRAM

INSPECTION PROCEDURE

1. PERFORM ACTIVE TEST BY INTELLIGENT TESTER

1. Operate the intelligent tester according to the steps on the display and select "ACTIVE TEST".

   METER 

   Item	Test Details	Diagnostic Note
   Fuel Meter Operation	OFF, EMPTY, 1/2, FULL	-

   OK:

   Needle indication is normal.
   

NG	REPLACE COMBINATION METER ASSEMBLY

OK

2. READ VALUE OF INTELLIGENT TESTER

1. Operate the intelligent tester according to the steps on the display and select "DATA LIST".

   METER 

   Item	Measurement Item/Range (Display)	Normal Condition	Diagnostic Note
   Fuel Input	Fuel input signal Min.: 0, Max.: 255	Fuel gauge indicates (F): 47 Fuel gauge indicates (1/2): 148 Fuel gauge indicates (E): 205	-

   OK:

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

OK	REPLACE COMBINATION METER ASSEMBLY

NG

3. INSPECT COMBINATION METER ASSEMBLY

1. Disconnect the fuel tank wire.

2. Shorten the terminals 3 (FE) and 4 (FS) on wire harness side.

3. Disconnect the battery (-) terminal, then reconnect.

4. Turn the ignition switch to the ON position.

   OK:

   Fuel receiver gauge indicates F or more.
   

OK	Go to step 6

NG

4. CHECK HARNESS AND CONNECTOR (BETWEEN COMBINATION METER AND FUEL TANK WIRE)

1. Disconnect the C9 connector and fuel tank wire.

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   C9-2 (FE) - C9-19 (FUEL SENDER)	Always	Below 1 Ω
   C9-19 (FUEL SENDER) - Body ground	Always	10 kΩ or higher

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR

OK

5. REPLACE COMBINATION METER ASSEMBLY

NG
REPLACE HYBRID VEHICLE CONTROL ECU

6. INSPECT FUEL TANK WIRE

1. Disconnect the fuel tank wire from the fuel sender gauge assembly.

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

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   2 (FS) - 4 (L2)	Always	Below 1 Ω
   3 (FE) - 3 (FE)	Always	Below 1 Ω
   4 (L2) - Body ground	Always	10 kΩ or higher

NG	REPLACE FUEL TANK WIRE

OK

7. INSPECT FUEL SENDER GAUGE ASSEMBLY

1. Check the operation of the float moving smoothly between F and E.

2. Disconnect the fuel sender gauge connector.

3. Remove the fuel sender gauge assembly.

4. Measure the resistance between the terminals 2 (FE) and 3 (FS) of connector according to the value(s) in the table below.

   Standard Resistance:

   Float Level	Resistance (Ω)
   F	13.5 to 16.5
   E	405.5 to 414.5

NG	REPLACE FUEL SENDER GAUGE ASSEMBLY

OK
