I got a "check fuel cap" message and my avg.mpg, range, and fuel gauge went screwy.

Asked by EMinFL Jan 04, 2017 at 11:50 AM about the 2011 Honda CR-V LX FWD

Question type: Maintenance & Repair

There was no correlation between mileage, avg mpg and range of miles.  I was getting readings of svg mpg of 30+ and range of over 450 miles.  The fuel gauge would read half full and I put 7-8 gallons in the tank.  The odometer still shows true mileage.  I the EVAP and sensors tested at a dealer, no error messages were generated.

Also happened to my 2013 CRV. Answer I found was either you have tightened the cap too much (beyond a couple of clicks) or need to replace it. It takes awhile for the message to clear up once you readjust the cap.
