Problem	Causes
DEFINITION: Difficulty when refueling the vehicle.
Difficult to fill	If the vehicle is equipped with dual fuel tanks and a single filler neck the flow of the fuel into the tanks may exceed the ability of the system to compensate, the fill nozzle will automatically shut off. The system will require 10-20 seconds to equalize pressure before filling can resume. Refer to Fuel System Description . The check valve is stuck closed. The fill limiter vent valve is stuck closed. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) . The evaporative emission (EVAP) canister is restricted. Refer to Evaporative Emission (EVAP) Canister Replacement . The EVAP canister vent solenoid is stuck closed. Refer to Evaporative Emission (EVAP) Canister Vent Solenoid Valve Replacement . Restricted EVAP pipes-Refer to Evaporative Emission (EVAP) Hoses/Pipes Replacement - Canister/Fuel Tank . High Reid vapor pressure High fuel temperature The fuel filler hose/pipe is pinched, kinked or blocked. Refer to Filler Tube Replacement . The fuel feed hose, or crossover hose, is pinched, kinked or blocked. Refer to Fuel Rail Assembly Replacement . The ignition switch is ON.
Over fill	The pressure relief valve in the fill limiter vent valve is stuck open. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) . The pressure relief valve in the fill limiter vent is valve leaking. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) . The fill limiter vent valve is stuck open. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) . The fill limiter vent valve is leaking. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) .
Premature shut-off of the fuel dispensing nozzle	The fill limiter vent valve is stuck closed. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) . The EVAP canister is restricted. Refer to Evaporative Emission (EVAP) Canister Replacement . The EVAP canister vent solenoid is stuck closed. Refer to Evaporative Emission (EVAP) Canister Vent Solenoid Valve Replacement . Restricted EVAP pipes-Refer to Evaporative Emission (EVAP) Hoses/Pipes Replacement - Canister/Fuel Tank . High Reid vapor pressure High fuel temperature The fuel filler hose/pipe is pinched, kinked or blocked. Refer to Filler Tube Replacement . The fuel feed hose, or crossover hose, is pinched, kinked or blocked. Refer to Fuel Rail Assembly Replacement . The ignition switch is ON.
Fuel spit back	The check valve is stuck open. The check valve is stuck closed. The check valve is leaking. High Reid vapor pressure High fuel temperature
Liquid fuel in the EVAP canister	The fill limiter vent valve is stuck open. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) . The fill limiter vent valve is leaking. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) .
Liquid fuel leak	The pressure relief valve in the fill limiter vent valve is stuck open. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) . The pressure relief valve in the fill limiter vent valve is leaking. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) . The fuel filler hose is loose or torn. Refer to Filler Tube Replacement . The fuel feed hose, or crossover hose, is loose or torn. Refer to Fuel Rail Assembly Replacement . The fill limiter vent valve is stuck open. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) .
Fuel odor	The pressure relief valve in the fill limiter vent valve is stuck open. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) . The pressure relief valve in the fill limiter vent valve is leaking. Refer to Fuel Tank Replacement (Front Tank) or Fuel Tank Replacement (Rear Tank) . The EVAP canister is saturated. Refer to Evaporative Emission (EVAP) Canister Replacement .
