If you notice a warning light indicating an issue with the emissions system in your 2019 Honda Civic, it means that one of the emissions sensors has detected a problem. These sensors are located after the catalytic converter and are responsible for monitoring the exhaust gas to ensure it has been properly cleaned. Typically, this issue can cause your vehicle to fail an emissions test in your state. It may also indicate a malfunction in the emissions control system or catalytic converter of your car. I recommend having a mechanic inspect the vehicle to check for any failed components, as it could also be related to a faulty sensor.
