Frequently Asked Questions About Emissions

What causes a vehicle to fail an emissions test? Vehicles commonly fail emissions testing due to an active check engine light, a defective catalytic converter, faulty oxygen sensors, or a leaking evaporative emission system that allows fuel vapors to escape.

Can you pass an emissions test if your check engine light is on? You cannot pass a state emissions inspection if your check engine light is illuminated. The testing facility will reject the vehicle automatically, making professional diagnostic repair your necessary first step.
