Specific to:

Honda Accord 2007

  1. Remove the access panel to expose the fuel pump assembly. For additional information, refer to the following section, -Fuel Pump, Removal and Installation.-
  2.  
  3. Disconnect the fuel pump wiring harness.
  4.  
  5. Measure the voltage between the fuel pump wiring harness terminals No. 1 and 2 with the ignition switch ON. There should be battery voltage.
  6.  
  7. If there is no voltage, check for a short in the yellow/black wire to ground. If there is voltage, proceed to the next step.
  8.  
  9. Remove the fuel pump assembly from the fuel tank. For additional information, refer to the following section, --Fuel Pump, Removal and Installation.-
  10.  
  11. Measure the resistance between fuel tank unit 5P connector terminals No. 1 and No. 2 with the float at the following positions:

    E (EMPTY): 770-790 ohms
     
    LOW (LOW FUEL INDICATOR): 487.9-617.1 ohms
     
    1 / 2 (HALF FULL): 205.4-215.5 ohms
     
    F (FULL) positions: 19-21 ohms
     

  12.  
  13. If the resistance is not within specifications, replace the fuel level sending unit.

  8.  
  9. Remove the fuel pump assembly from the fuel tank. . For additional information, refer to the following section, --Fuel Pump, Removal and Installation.-
  10.  
  11. Measure the resistance between fuel tank unit 5P connector terminals No. 1 and No. 2 with the float at the following positions:

    E (EMPTY): 772-788 ohms
     
    LOW (LOW FUEL INDICATOR): 503.8-589.4 ohms
     
    1 / 2 (HALF FULL): 205.4-215.5 ohms
     
    F (FULL) positions: 19-21 ohms
     

  12.  
  13. If the resistance is not within specifications, replace the fuel level sending unit.
