Orange EML light - Tightening Fuel Cap ....Really a Solution???

[Juliand]

Apologies, for wrong place, but of interest potentially..... My son's 03 Civic had EML Amber light on dash, so did a quick search on google and first thing to try was checking that the fuel filler cap was on tight (?). I couldn't really see this fixing it, so called Honda for price on plug in diagnostic and they said it could be so many things, so best to bring it in (£65 to plug in). In the meantime, tried the aforementioned fuel cap, and after a couple of journeys, it's actually gone out now. Hmmm! It might come back on, of course, but could it really be this being the problem???

Thoughts, please chaps, and any obvious things if this doesn't prove to be the proper solution. Obviously something to do with engine emissions somewhere.

Cheers

He hadn't just filled it right to the brim by any chance had he?

No, he never has that much money, ha ha.  Seems a curious fix - see how it goes over the next few weeks.

If Civics have the carbon can and purge valve under the car near the petrol tank, they can get pretty crusted up down there.   Need to get it fault coded really to see which part it's moaning about, and if it's a big leak or a small leak.  Japanse and US cars tend to be quiet granular with emissions fault coding due to the uber strict Californian emissions regs.   German cars just report 'a' leak, not varying degrees of leak like those cars do.
