What Happens During A Smog Test?

Is your car overdue for a smog check? Are you even sure what a smog check is? Never fear, your friends at Ray Chrysler Jeep Dodge Ram are here to break it down for you.

 

A smog check measures your vehicle for emissions including carbon monoxide (CO), carbon dioxide (CO2), hydrocarbons (HC) and oxygen (O2). In cities like the ones surrounding Fox Lake Chrysler Dodge Jeep Ram dealer lots, smog checks will also measure levels of oxides of nitrogen (NOx) since pollution is more prevalent in urban areas.

 

During the smog check, your technician will attach measuring equipment to your vehicle to ensure that your car’s emissions equipment is in place, functioning and doing its absolute best to weed out pollutants from your car’s exhaust.

 

A smog check consists of an emissions inspection, a visual inspection and a functional inspection. During the test, measurements are taken through the attachment device, recorded and made available to the government agency responsible for monitoring smog and vehicle emissions.

 

Two testing methods are typically used. The first is the Two-speed Idle (TSI) test, which analyzes exhaust emission from your car’s tailpipe as the engine idles at high and low speeds. The other test is the Acceleration Simulation Mode (ASM) test, which is usually used on older vehicles. The ASM test measures emissions using a device called a dynamometer to place your vehicle under simulated driving conditions.

 

Newer cars, including those currently available at a Chrysler Dodge Jeep Ram dealership near you, typically use on-board diagnostics (OBDI) to allow technicians to download information from your vehicle’s on-board diagnostics computer.

 

If your car fails the smog check, you can get it repaired at a licensed test and repair station before submitting to another test. Don’t delay getting those repairs done–vehicles that fail the inspection are not allowed on public roads and you’ll get a ticket if you’re caught operating a car that hasn’t passed its inspection.
