Component Testing

  1. Ignition OFF, disconnect the harness connectors at the fuel level sensor.
  2. Sweep the fuel level sensor through its full range of motion while measuring resistance between the signal terminal and the low reference terminal listed below:
    • Signal Terminal C (5.3L)
    • Low Reference Terminal B (5.3L)
    • Signal terminal B (4.3L, 4.8L or 6.0L)
    • Low Reference Terminal C (4.3L, 4.8L or 6.0L)
    • Signal Terminal B (6.6L Diesel)
    • Low Reference Terminal C (6.6L Diesel)
  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.

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