Component Testing

  1. Ignition OFF/Vehicle OFF, remove the fuel level sender.
  2. Sweep the fuel level sensor through its full range of motion while measuring resistance between the signal terminal 5 and the low reference terminal 6.
  3. Test for a minimum resistance value of 37-43 Ω and a maximum value of 245-255 Ω without any spikes or dropouts.
    • If minimum resistance is not 37-43 Ω, maximum resistance is not 245-255 Ω, or if there are any spikes or dropouts 

      Replace the fuel level sensor.

    • Go to next step: If minimum resistance is 37-43 Ω, maximum resistance is 245-255 Ω, and if there are no spikes or dropouts 
  4. All OK.
