What Does Hefti Automotive Service 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, Hefti Automotive Service 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.
