How I fixed the “Emissions System Problem” on my Honda

So less than four months after buying my Honda, an “Emissions System Problem” showed up on my dash when I started up the car one morning before work.

Wut?! How can a brand new car already have problems?

Turns out there’s an easy fix.

I texted Sandy (who’s an automotive service writer), who calmly replied:

Did you just put fuel in the car? Check and tighten gas cap.

Lo and behold, it worked!

Turns out (and the gas cap is actually labeled as such), you need to twist the gas cap clockwise until you hear a click to properly close it. I twist it until I hear two clicks, for good measure.

All good now.

Lesson learned: always get a second opinion on car troubles before you take it in for service. Talk to a friend in the business. Google it. Save yourself time, hassle, and most importantly, money!

    I drive a 2016 and it doesn’t have a gas cap. The fuel door basically works as the gas cap in a way.
