Q: Why does my check engine light still come on in my 2014 Hyundai Accent even after changing the fuel cap

asked by on April 27, 2017

gas cap has been replaced but the light comes on even after reset

My car has 60000 miles.
My car has an automatic transmission.

Hello. The gas cap will not repair the issue unless that is the problem. Depending on what code is coming up will determine what is needed. I would start by scanning the computer for codes first to see what may be going on. If the code is a small leak in the evap system then it may be caused by a solenoid that is leaking or a hose that is leaking.
