Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

PERFORM ACTIVE TEST BY TECHSTREAM (FUEL METER OPERATION)

Connect Techstream to the DLC3.
Turn the ignition switch ON.
Turn the tester on.
Enter following menus: Body Electrical / Combination Meter / Active Test.

Check the operation by referring to the table below.

Combination Meter:

CONTROL RANGE CHART

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

OK: Go to next step

READ VALUE OF DATA LIST (FUEL INPUT)

Connect Techstream to the DLC3.
Turn the ignition switch ON.
Turn the tester on.
Enter following menus: Body Electrical / Combination Meter / Data List.

Check the values by referring to the table below.

Combination Meter:

MEASUREMENT ITEM/RANGE CHART

Tester Display	Measurement Hem/Range	Normal Condition	Diagnostic Note
Fuel Input	Fuel input signal Min.: 0, Max.: 127.5	Fuel gauge indicates (F): 33 Fuel gauge indicates (3/4): 98 Fuel gauge indicates (1/2): 144 Fuel gauge indicates (1/4): 179 Fuel gauge indicates (E): 206	-

OK:

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

NG: REPLACE COMBINATION METER ASSEMBLY

OK: Go to next step

INSPECT FUEL SENDER GAUGE ASSEMBLY

Remove the fuel sender gauge.

Measure the resistance of the gauge.

Standard resistance

STANDARD RESISTANCE

Tester Connection	Float Level	Specified Condition
1 - 2	F	15.0+-1.5 Ω
1 - 2	1/2	212.5 +-12.2 Ω
1 - 2	E	410.0 +-4.5 Ω

NG: REPLACE FUEL SENDER GAUGE ASSEMBLY

OK: Go to next step

CHECK WIRE HARNESS (COMBINATION METER - FUEL SENDER GAUGE ASSEMBLY)

Disconnect the E19 meter connector.
Disconnect the S2 gauge connector

Measure the resistance of the wire harness side connectors.

Standard resistance

STANDARD RESISTANCE

Tester Connection	Specified Condition
E19-25 (L) - S2-1 (FS)	Below 1 Ω
E19-12 (E) - S2-2 (EF)	Below 1 Ω
E19-25 (L) or S2-1 (FS) - Body ground	10 kΩ or higher
E19-12 (E) or S2-2 (EF) - Body ground	10 kΩ or higher
