What to do when the OBD light comes on?

When the OBD light comes on, it indicates issues such as emissions not meeting standards, incomplete combustion, reduced power, and high fuel consumption. While you can continue driving, it is recommended that the owner repairs the vehicle as soon as possible. OBD, translated as On-Board Diagnostics in Chinese, is a system that continuously monitors the engine's operating conditions and the working status of the exhaust after-treatment system. It will immediately issue a warning if it detects any condition that may cause excessive emissions. When the ignition switch is turned on, the OBD indicator light will illuminate, initiating a system check, and it will turn off after the engine starts. If a fault affecting engine performance and emissions occurs while driving, the OBD light will illuminate. Possible causes include issues with the air filter or its connections, as well as fuel quality and weather conditions. Check if the air filter box is stuck, reinstall it, or try turning the engine off and restarting it.
