Fuel Receiver Gauge Malfunction [08/2013 - ]: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
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	OFF, Empty, 1/2, Full	-

   OK

   Fuel receiver gauge indication is normal.

NG → See step   6 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
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 G, Max.: 127.5 G	Fuel receiver gauge indicates F: 57.9 G	-
   		Fuel receiver gauge indicates 3/4: 48.3 G
   		Fuel receiver gauge indicates 1/2: 32.2 G
   		Fuel receiver gauge indicates 1/4: 16.1 G
   		Fuel receiver gauge indicates E: 6.4 G

   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

B → See step   6 

A: Go to next step 

1. Disconnect the H14 combination meter assembly connector.
2. Disconnect the P7 fuel suction tube with pump and gauge assembly connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   H14-26 (FR) - P7-2 (FS)	Always	Below 1 Ω
   H14-26 (FR) - Body ground	Always	10 kΩ or higher
   H14-27 (FE) - P7-3 (FE)	Always	Below 1 Ω
   H14-27 (FE) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Remove the fuel sender gauge assembly. Refer to REMOVAL [08/2013 - ] .

2. Check that the float moves smoothly between F and E.
3. Check if the fuel sender gauge arm is deformed.
4. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   1 - 2	Float level is F (upper)	13.5 to 16.5 Ω
   1 - 2	Float level is between F (upper) and E (lower)	13.5 to 414.5 Ω (Gradually changes)
   1 - 2	Float level is E (lower)	405.5 to 414.5 Ω

OK: Go to next step 

1. Visually check for deformation on the fuel suction tube with pump and gauge assembly connector.

   OK

   There is no deformation.

NG → See step   8
