FUEL SENDER GAUGE ASSEMBLY INSPECTION

PROCEDURE

1. 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).

         Tech Tips

         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) 4.255 to 4.605 V* Float position is E (lower) 0.345 to 0.695 V*

         
         

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

         Tech Tips

         
         

         • Output voltage(F) = (0.851 x Voltage applied to terminals) to (0.921 x Voltage applied to terminals)

         • Output voltage(E) = (0.069 x Voltage applied to terminals) to (0.139 x Voltage applied to terminals)

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

2. INSPECT NO. 2 FUEL SENDER GAUGE ASSEMBLY

   
   

   1. Check the No. 2 fuel sender gauge assembly output voltage.

      
      
      1. 

         *a	Component without harness connected (No. 2 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 No. 2 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).

         Tech Tips

         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 (No. 2 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) 4.255 to 4.605 V* Float position is E (lower) 0.345 to 0.695 V*

         
         

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

         Tech Tips

         
         

         • Output voltage(F) = (0.851 x Voltage applied to terminals) to (0.921 x Voltage applied to terminals)

         • Output voltage(E) = (0.069 x Voltage applied to terminals) to (0.139 x Voltage applied to terminals)

         If the result is not as specified, replace the No. 2 fuel sender gauge assembly.
