  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. With a scan tool, observe the Fuel Tank Level Remaining parameter in the powertrain control module (PCM) Enhanced evaporative (EVAP) data list.
Does the scan tool indicate that the Fuel Tank Level Remaining parameter is greater than the specified value?		 98% Go to Step 3  Go to Diagnostic Aids

  1. Turn OFF the ignition.
  2. Disconnect C105.
  3. Connect a 3-amp fused jumper wire between the signal circuit of the fuel level sender and the low reference circuit of the fuel level sender on the female terminal side of the connector.
  4. Turn ON the ignition, with the engine OFF.
  5. With a scan tool, observe the Fuel Tank Level Remaining parameter.
Does the scan tool indicate that the Fuel Tank Level Remaining parameter is less than the specified value?		 4% Go to Step 6  Go to Step 4 
4 Test the signal circuit of the fuel level sender for an open, a high resistance, or a short to voltage. Refer to Circuit Testing andWiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 12  Go to Step 5 
5 Test the low reference circuit of the fuel level sender for an open, a high resistance, or a short to voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 12  Go to Step 9 
6 Test the signal circuit of the fuel level sender for an open, a high resistance, or a short to voltage between C105 and the fuel level sender. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 12  Go to Step 7 
7 Test the low reference circuit of the fuel level sender for an open, a high resistance, or a short to voltage between C105 and the fuel level sender. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 12  Go to Step 8 
8 Inspect for poor connections at the harness connector of the fuel level sender. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 12  Go to Step 10 
9 Inspect for poor connections at the harness connector of the PCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 12  Go to Step 11 
10 Replace the fuel level sender. Refer to Fuel Sender Assembly Replacement in Engine Controls - 6.0L.
Did you complete the replacement?		 - Go to Step 12  -
11 Replace the PCM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming.
Did you complete the replacement?		 - Go to Step 12  -

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
