WARNING: This page is about a different variant/trim than selected.
  1. CHECK FOR AN ACTIVE DTC 
    1. Turn the ignition on.
    2. With the scan tool, read DTCs and record on the repair order.

      Is the DTC active or pending?

      Yes 

      • Go To  3

      No 

      • Go To  2
  2. MONITOR THE PRIMARY FUEL LEVEL SENSOR VOLTAGE READING FOR AN OPEN SPOT ON THE SENSOR 
    WARNING:

    The fuel system is under a constant pressure (even with the engine off). Before testing or servicing any fuel system hose, fitting or line, the fuel system pressure must be released. Failure to follow these instructions can result in possible serious or fatal injury.

    1. Disconnect the fuel supply line at the fuel rail.
    2. Connect a drain hose between the fuel supply line and an approved fuel container.
    3. Turn the ignition on.
    4. Remove the Fuel Pump Relay from the PDC.
    5. Connect a jumper across terminal 30 and terminal 87 of the Fuel Pump Relay connector to actuate the Fuel Pump Assembly until all fuel is removed from the Fuel Tank.
    6. Remove the jumper when there is no more fuel coming out of the hose.
      NOTE:

      When the Fuel Tank is completely empty, the Fuel Level Sensor should read at or near empty (indicated by a voltage reading of approximately 4.3-4.5 volts) on the scan tool. If the Fuel Tank is near full, the scan tool should read approximately 0.6 volts on the scan tool.
