Fuel Receiver Gauge Malfunction: Procedure

1. Check if CAN communication DTC is output. Refer to DIAGNOSIS SYSTEM .

   Result

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

B → See step   7 

A: Go to next step 

1. Connect Techstream 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 → See step   8 

OK: Go to next step 

1. Connect Techstream 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 → See step   8 

OK: Go to next step 

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: Go to next step 

1. Disconnect the fuel sender gauge connector.

2. Measure the resistance between the 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 111.0 (Gradually changes)
   E	109.0 to 111.0

3. Remove the fuel sender gauge assembly. Refer to REMOVAL - Step 2 for 2GR-FE. Refer to REMOVAL for 1AR-FE.
4. Check that the float moves smoothly between F and E.
5. Check the fuel sender gauge if there is deformation in the arm.

   Result

   Result	Proceed to
   OK	A
   NG (for 2GR-FE)	B
   NG (for 1AR-FE)	C

B → See step   9 

C → See step   11 

A: Go to next step 

1. Replace the combination meter assembly with a new one or a normal one. Refer to REMOVAL - Step 3 .

   OK

   The operation of the combination meter assembly returns to normal.

   Result

   Result	Proceed to
   OK	A
   NG (for 2GR-FE)	B
   NG (for 1AR-FE)	C

B → See step   10 

C → See step   12
