There are many components that work together to ensure your vehicle produces low emissions. It can be something as simple as a vacuum leak or faulty PCV valve, or even a faulty oxygen sensor or catalytic converter. If you didn’t pass the smog test, it is likely that your Check Engine Light is on, indicating a diagnostic trouble code that is stored. A certified technician, like one from YourMechanic, will be able to scan your vehicle and look at the data to determine the exact cause of your concern.
