My 2013 Jeep Grand Cherokee had a check engine light on. I've taken it to Pep Boys and AutoZone, they will both use a code reader and give you the error code for free. My trouble code was P0456, which is a very small evap leak. System. They both told me it's usually fixed by making sure the gas cap is screwed on properly, or if that doesn't work, replacing the cap. Tightening the gas cap didn't help, so I bought that. I took my car back to AutoZone, they used a code reader and it fixed the leak that was causing the error. Very glad I didn't have to hire him as a mechanic.
