Ianmark Posted July 28, 2017 Report Share Posted July 28, 2017 (edited) My 08 Edge has had the gas cap light on since I have ad the car (4 months), and I pull 0 codes when I scan the car. I changed the gas cap and drove for 3 days with the new cap and the light never went out. Since the gas cap light is not part of the OBD2 codes and my scanner won't read a fault, is going to the dealer the only way to get rid of the light? I have checked around the forum and Google, but didn't really find anything useful. Normally, I would erase any codes and see if it comes back after a repair or part replacement, but I can not do that with the Edge. Any help would be great. Thanks, Ian Edited July 28, 2017 by Ianmark Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted July 28, 2017 Report Share Posted July 28, 2017 Very likely the EVAP purge valve (at the firewall) needs to be replaced. Vacuum test like macbwt shows on his YT channel. That is the quickest way to tell. If the purge valve is fine, then possibly the filler neck has an issue. Thriller Trailer 1 Quote Link to comment Share on other sites More sharing options...
