Check Fuel Fill Inlet warning

Recommended Posts

This system has been in use since 2009, or maybe even earlier. The Lincoln MKS has it, and all the Fords I have owned since 2010 had it, and never had a problem. The problems you are hearing about are not the capless system, but the fuel venting system.

The Venting system is part of the capless system, it closes the tank off after filling so the Evap system can contain the fumes. When there is a problem it is usually due to a valve sticking open so the sensors dont detect pressure in the tank and set the check engine. Same is if you left the cap off a regular system.

I just thought I'd elaborate on this subject since a couple of us have had these Dash Display Warnings in very different weather conditions.

Hybridbear's instance was in very cold, ice and snow and mine was in fair weather.

 

I tried resetting mine with the FFH's little funnel that is included and carried under the mat in the trunk.

The procedure is in the FFH Owner's manual.

Yesterday, close to noon, I started my car, only to get this Check Fuel Fill Inlet warning... It was about 95 degrees out, so I'm also thinking weather is not a good predictor.

 

At the time, all I could think to do was check it by hand - literally pushing my finger in, which came out smelling like gas. :drop: Drove home with the windows down!

 

Found this thread last night, and tried the funnel procedure before heading out this morning. Upon starting the car, the message appeared again, and this time it was joined by the Service Engine Soon indicator light... Drove to work, parked, worked, and came out later to head home. Upon starting this time, the initial warning message did NOT appear, but the SES light remained on. I had to make a stop on the way home, and upon the next restart, the SES light was gone, too. I'm hoping it stays this way!

Prior to the capless system, if you left the gas cap loose or off it would set that light. Most likely the flap stuck in the neck to set the first light, pressure did not build up in the tank like it should and set the second light. Since the first went off, the vent had closed, pressure returned to normal and after the 3rd restart the SES went off. Code will still be stored for a while so if you run a VHR it should list it.

A code in the VHR? I ran two reports and never saw a code. Do you mean a specific code to describe the current/recent fault condition? All I see is "Service Required" under the "Engine, Transmission, & Emissions" section.

VHR wont show the code, but will recommend service if there are any codes stored, which by what you saw is what happened.
