Does your state require vehicle emissions testing (smog checks)? Smog check engine repairs are one of the many services offered.
During an emissions test, a certified mechanic will assess your vehicle’s tail pipe emissions and measure the amount of hydrogen, oxygen, carbon monoxide and nitrogen oxide present.
Emissions testing and smog checks take approximately one hour. The test ensures that your vehicle is not emitting harmful pollutants into the air. If a vehicle fails an emissions inspection, it may indicate that something is wrong with your vehicles emissions control system and an engine repair service might be needed.
