What happens during a smog check? A trained technician must perform a smog check at a licensed smog shop. If you reside in California, you can get a smog check near Vacaville. There are four stages of a smog check: 1. Visual Examination Your vehicle’s emission control systems and component are visually checked to confirm that they are correctly connected. This is usually the shortest part of the test. 2. Functional Inspection The technician inspects your vehicle’s exhaust gas cap, ignition timing, fuel evaporation system, and check engine light. This step takes more time and is more in-depth. If all components function properly, your vehicle may proceed to the next stage of the test. 3. OBD Inspection Modern cars have an On-Board Diagnostics (OBD) system which they use to self-diagnose and report problems within the vehicle. The technician obtains the required information from the OBD. The data is transmitted to the Bureau of Automobile Repair (BAR). Based on the information received, the BAR determines whether the vehicle is functioning properly. If so, the smog check moves on to the final stage. 4. Tailpipe Emissions Inspection There is a permissible level of emissions that no vehicle may exceed. The emissions measured from the tailpipe include hydrocarbons, carbon monoxide, carbon dioxide, oxides of nitrogen, and oxygen. If your vehicle fails any of the inspections, you will be advised on necessary repairs so it can pass when you try again. If your vehicle passes every step you will be issued a Certificate of Compliance. You will also receive a copy of the Vehicle Inspection Report for the smog check. Why do I need a smog check?
