What Does Greg's Auto Service and Repair Do During a Smog Check?

We inspect your car or truck's emissions-control equipment to measure the number of pollutants your vehicle is emitting.

First, Greg's Auto Service and Repair will analyze your car or truck's OBD computer system, emissions-control system, and check engine light codes for standard warnings that your emissions system is no longer functioning properly.

Next, we will inspect your car or truck's gas cap, ignition timing, exhaust gas recirculation system, fuel, and evaporative system.

Finally, we will perform a Tailpipe Emissions Inspection which measures the type and quantity of any pollutant emitted from your vehicle's tailpipe.

Did You Pass Your Smog Test?

Great! If your vehicle passes a smog check, Greg's Auto Service and Repair will provide you a vehicle inspection report showing your vehicle's results and will electronically send the smog certificate to DMV.
