Honda CR-V Check Engine Light on Due to Binding Fuel Cap
A binding fuel filler cap can cause the Check Engine Light to illuminate. Our technicians tell us this can be caused by a problem with the fuel filler neck which may require replacement.
I tighten the fuel cap down good and snug at fill up. Once I hit about half a tank the light goes on again..Take off cap, reinstall and tighten and the light goes out. It must be a pressure drop in the system causing this. Is there any place I should look to find the leak?... - Visitor
My check engine light will not go off and the reason is to check the fuel cap. I have replaced and tightened this cap numerous times. Now and alert (where my mileage shows) consistently says "check fuel cap". Whats up!! - Visitor

Gas cap binds and will not seal causing "check engine" lite to illuminate. Purchased a new gas cap - did not fix problem, still binding. Notified Superstition Springs Honda in Mesa, AZ of the problem - they had no recommendation for a fix. Problem still not fixed 3 years later - spraying with WD-40 or equivalent helps temporarily. Current mileage is 82,214. Honda should issue a recall for this problem. - Visitor
P1456 code readout on OBD reader. I noticed that the small, recessed black rubber gasket in the filler cap has a small split at one point. This is probably destroying the pressure seal. At any rate, I'm going to replace the cap. Nothing wrong with the filler neck, its clean and no burrs. I suspect others may have the same issue? - Visitor
Every time the check engine light comes on, it turns out to be the gas cap issue. I haven't fixed it and I ignore the light unless I experience some other symptoms or I am at the oil change place that reads the code for free. - Visitor
First the check fuel cap light flashed at me. I was driving and waited to check it. Next time I started the car the check engine light came on. Based on the reports here, I assume it's related to the fuel cap...will take it in for a check, but seems a bit clear what the issue is. - Visitor
