Troubleshooting the Check Fuel Fill Inlet Warning in a Ford Explorer: Causes, Fixes and Final Thoughts

If you own a Ford vehicle and have recently come across a “Check Fuel Fill Inlet” message on your dashboard, don’t worry, you’re not alone. This message is part of the new Ford “no gas cap” system and is often an indication of an error within the system.

The no gas cap system was designed to streamline the fueling process by eliminating the need for a traditional gas cap. However, it’s not without its issues, and the “Check Fuel Fill Inlet” message is one of the most common ones that Ford vehicle owners encounter.

Possible Causes

When you see the “Check Fuel Fill Inlet” message, it means that the onboard computer is not detecting the closure of the gas inlet door. This could be due to several reasons, including:

  • Debris or dirt on the inlet
  • A bad seal or locking filler plug
  • An evap leak
  • A faulty sensor indicating that the door is shut


The most common fix for this issue is to start by cleaning the area around the fuel fill inlet. There’s a small door that can be opened to inspect for any obstructions, and a small tube located in the trunk can be used to clear out any blockages. After cleaning, it’s important to ensure that the door is closing correctly and isn’t damaged in any way.

If cleaning the area doesn’t resolve the issue, it’s recommended to drive the vehicle for 5-10 miles to see if the message clears. If it doesn’t, there may be a more complex problem with the evap system, such as a faulty sensor or wiring issues.

If the message persists, it’s advisable to use an OBD2 scan tool to check for any error codes related to the evap system. Auto parts stores usually offer free scans, and this can help pinpoint the specific issue causing the message to appear.

Final Thoughts

If you’re experiencing the “Check Fuel Fill Inlet” message in your Ford vehicle, the first step is to clean the area around the fuel fill inlet and ensure proper closure. If the issue persists, further diagnostics may be necessary to identify and resolve any underlying problems with the evap system or sensors.
