   INSPECT FUEL SENDER GAUGE ASSEMBLY

   
   

   1. Check the fuel sender gauge assembly output voltage.

      
      
      1. 

         *a	Component without harness connected (Fuel Sender Gauge Assembly)
         *b	Voltage applied between terminals

         Apply 5 V between terminals 1 (FV) and 2 (FE).

         Note:
         

         • Be careful when connecting the leads, as the fuel sender gauge assembly may be damaged if the leads are connected to the wrong terminals.

         • Do not apply more than 6 V to terminals 1 (FV) and 2 (FE).

         Tip:

         If a stable power supply is not available, use 4 1.2 V nickel-metal hydride batteries or equivalent.

      2. 

         *a	Component without harness connected (Fuel Sender Gauge Assembly)

         Measure the voltage according to the value(s) in the table below.

         Standard Voltage
         Tester Connection Condition Specified Condition 2 (FE) - 3 (FR) Float position is F (upper) 4.25 to 4.61 V* Float position is E (lower) 0.34 to 0.70 V*

         
         

         • *: The output voltage changes depending on the voltage applied to the terminals.

         Tip:
         

         • Output voltage (F) = (0.850 x Voltage applied to terminals) to (0.922 x Voltage applied to terminals)

         • Output voltage (E) = (0.068 x Voltage applied to terminals) to (0.140 x Voltage applied to terminals)

         If the result is not as specified, replace the fuel sender gauge assembly.
