Diagnostic Test

  1. DTC IS ACTIVE 
    NOTE: Diagnose any Fuel Level DTCs before proceeding with this test.
    NOTE: The following test must be performed on both Fuel Level Sensors.
    1. Inspect the Fuel Pump Module harness connectors for any corrosion or damage.
    2. Start the engine and allow it to reach normal operating temperature.
      WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.
    3. With the scan tool, select View DTCs.

      Is the status Active for this DTC?

      Yes 

      • Go to step  2

      No 

  2. FUEL TANK INSPECTION 
    1. Inspect both sides of the Fuel Tank for any damage that may restrict the Fuel Level Sensor float.

      Were any problems found?

      Yes 

      No 

      • Go to step  3
  3. FUEL LEVEL SIGNAL CIRCUIT SHORTED TO GROUND 
    1. Turn the ignition off.
    2. Disconnect the Fuel Pump Module harness connector.
    3. Measure the resistance between ground and each Fuel Level Signal circuit at the Fuel Pump Module harness connector.

      Is the resistance below 100 ohms?

      Yes 

      No 

      • Go to step  4
  4. FUEL LEVEL SIGNAL CIRCUIT OPEN OR HIGH RESISTANCE 
    1. Disconnect the Cluster harness connector.
    2. Measure the resistance of each Fuel Level Signal circuit from the Fuel Pump Module harness connector to the Cluster harness connector.

      Is the resistance below 5.0 ohms?

      Yes 

      • Go to step  5

      No 

  5. (Z965) GROUND CIRCUIT OPEN OR HIGH RESISTANCE 
    1. Measure the resistance between ground and the (Z965) Ground circuit in the Fuel Pump Module harness connector.

      Is the resistance below 5.0 ohms?

      Yes 

      • Go to step  6

      No 

  6. FUEL TANK AND SIPHON HOSE INSPECTION 
    WARNING: The fuel system is under a constant pressure even with the engine off. Before opening the fuel system, the fuel pressure must be released in accordance with the service information. Failure to follow these instructions can result in possible serious or fatal injury.

    Inspect the following components:

    • Siphon hose for restrictions or being disconnected.
    • Siphon Inlet and Outlet tube on the Fuel Modules for restrictions.
    • Fuel Pump Inlet Strainers for restrictions.
    • Fuel Tank for any obstructions or deformities.
    • Fuel Pump Module Float arm for damage.

    Were any problems found?

    Yes 

    No 

    • Go to step  7
  7. FUEL LEVEL SENSOR RESISTANCE 
    NOTE: The following test must be performed on both Fuel Level Sensors.
    1. Move Fuel Level Sensor float to its lowest point of travel.
    2. Measure the resistance between the terminals of the Fuel Level Sensor.
      NOTE: The resistance should be approximately 120 ohms (93 ohms for Flex fuel vehicles) with the float at its lowest point of travel (empty).
    3. Move the Fuel Level Sensor float to its highest point of travel.
    4. Measure the resistance between the terminals of Fuel Level Sensor.
      NOTE: The resistance should be approximately 13 ohms with the float at its highest point of travel (full).

      Is the resistance of the sensor within the values described above?

      Yes 

      No
