Component Function Check

1. Turn ignition switch OFF.
2. Disconnect fuel level sensor unit and fuel pump (main) connector and fuel level sensor unit (sub) connector.
3. Connect variable resistor between harness connector terminals located on the vehicle side of the fuel level sensor unit and fuel pump (main) and fuel level sensor unit (sub).

   Fuel level sensor unit and fuel pump (main)			Fuel level sensor unit (sub)
   Connector	Terminals		Connector	Terminals
   B102	3		B97	2

4. Set variable resistor according to the resistance value shown in the following table and turn ignition switch ON.

   Resistance (Ω)* (Approx.)	Fuel gauge indication position (Approx.)
   Less than 98	Full
   186	1/2
   232	1/4
   255	1/8
   More than 275	Empty

   * : Reference resistance values used when the combination meter judges the indication position of the fuel gauge.

Is the inspection result normal?

YES 

GO TO STEP 2. 

NO 

Refer to DIAGNOSIS PROCEDURE .

Check the fuel level sensor unit and fuel pump (main) and/or fuel level sensor unit (sub). Refer to COMPONENT INSPECTION .

Is the inspection result normal?

YES 

INSPECTION END

NO 

Replace the fuel level sensor unit and fuel pump (main) and/or fuel level sensor unit (sub). Refer to REMOVAL AND INSTALLATION .
