does check engine light fail emissions

Certainly! The "Check Engine" light illuminates on your dashboard primarily as a warning that your vehicle's engine or related systems are experiencing issues. This can significantly affect the emission levels. In most regions, a lit Check Engine light will indeed cause a vehicle to fail emissions tests. The reason is that the illuminated light often indicates issues like faulty oxygen sensors, loose gas caps, or more severe engine problems, all of which can lead to increased emissions. Before taking an emissions test, it's recommended to have any issues causing the Check Engine light to illuminate addressed by a professional. This not only aids in passing emissions tests but also ensures your vehicle is operating efficiently and environmentally friendly.
