Possible Sources
- Fuel tank filler pipe vent tube
- Fuel tank filler pipe
- EVAP system
- Fuel tank inlet check valve (part of the fuel tank)
- Fuel level vent valve, if equipped (part of the fuel tank)
- A1 VISUALLY INSPECT MECHANICAL COMPONENTS
- Inspect to determine if any of the following mechanical concerns apply:
- Bent, kinked or damaged fuel tank filler pipe
- Bent, kinked or damaged fuel tank filler pipe vent tube
- Incorrect routing of the fuel tank filler pipe
- Incorrect routing of the fuel tank filler pipe vent tube
- Incorrect position of fuel tank filler pipe clamps
- Incorrect position of fuel tank filler pipe vent tube clamps
- Fuel fill hose indexing mark not lined up with tank indexing mark
- Fuel tank mounted vapor tubes bent or damaged

- EVAP system fresh air tube plugged (dirt, spider webbing)
Was the cause of the concern found?
Yes REPAIR or INSTALL new components to correct the concern. No GO to A2 - Inspect to determine if any of the following mechanical concerns apply:
- A2 RETRIEVE DTCS
- Using a scan tool, perform the PCM self-test.
- Are any DTCs present?
Were DTCs retrieved on-demand during self-test?
Yes Refer to Engine Controls - Diagnostic Methods (Except Diesel & Hybrid) . No GO to A3 - A3 CHECK THE FUEL TANK FILLER PIPE ASSEMBLY FOR BLOCKAGE OR RESTRICTION
- Remove the fuel tank filler pipe assembly. Refer to: Fuel Tank Filler Pipe .
- Inspect the fuel tank filler pipe and fuel tank vent tube for a blockage or restriction.
Is the fuel tank filler pipe or fuel tank vent tube blocked or restricted?
Yes If possible, REPAIR the blockage or restriction. If the blockage or restriction cannot be repaired, INSTALL a new fuel tank filler pipe. Refer to: Fuel Tank Filler Pipe . No GO to A4 - A4 CHECK THE FUEL TANK INLET CHECK VALVE
- Inspect the fuel tank inlet check valve for restriction or sticking.
Is the fuel tank inlet check valve restricted or sticking?
Yes If possible, REPAIR the restriction. If the restriction cannot be repaired, INSTALL a new fuel tank. Refer to: Fuel Tank . No INSTALL a new fuel tank. Refer to: Fuel Tank .
