nate39 Posted April 6, 2024 Report Share Posted April 6, 2024 Hi, I bought a 2020 Edge Titanium back in February. The dealer I bought it from is two hours away and so that is why I don't just take it to them to look at. My problem is that about every 2 or 3 weeks the check engine light comes on. I have a code reader and it is saying that there is a very small leak in my evap, I erase the code but it comes back like I said. I don't think it is my gas cap since it doesn't have a cap. Is the only way to find a leak to do a smoke test at the car shop? I don't want to spend money replacing parts that are okay. thanks for any help.

Blk22Edge Posted yesterday at 02:30 PM Report Share Posted yesterday at 02:30 PM A common failure is the purge valve as well. I'd check there. I had a small leak and it was my purge valve leaking internally. Unless commanded by the computer it's supposed to hold vacuum and mine did not. To test it, unplug the purge valve electrical connector and disconnect the vacuum line coming out of the valve. Start the engine. If vacuum is present, I'd suspect a bad valve.
