Component Function Check

1. Turn ignition switch OFF.
2. Disconnect fuel level sensor unit and fuel pump (main) 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 the fuel level sensor unit (sub).

   Fuel level sensor unit and fuel pump (main)		Fuel level sensor unit (sub)
   Connector	Terminal	Connector	Terminal
   B241	5	B21	1

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

   Resistance (Ω)(1) (Approx.)	Fuel gauge indication position (Approx.)
   Less than	94 Full
   140	3/4
   186	2/4
   232	1/4
   More than 278	Empty
   (1) Reference resistance values used when the combination meter judges the indication position of the fuel gauge.

   Is the inspection result normal? 

   YES: GO TO 2.

   NO: Refer to "DIAGNOSIS PROCEDURE ".

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

Is the inspection result normal? 

YES: INSPECTION END

NO: Replace fuel level sensor unit and fuel pump (main) or fuel level sensor unit (sub). Refer to "REMOVAL AND INSTALLATION ".
