I have a Hyundai Accent 2005. I diagnosed it for a check engine light, and the code was P0442. The guy at AutoZone told me i needed to replace the fuel cap. I bought a new one and the check engine light is still on. What could be the problem? Thank you
Did you reset?fill up a tank and reset, and see what happen.
Testimonial: "Do you mean fill up a tank of gas? how to reset it?"
What do you mean by reset?
Is it just full up the tank with gas?
Go to auto zone to reset the code they do for free.
Could be a small leak in the fuel system if can not fix is OK do not worry.
