Colorado State Vehicle Inspection at Larry H. Miller Nissan

Colorado State Inspection at Larry H. Miller Nissan Highlands Ranch

The state of Colorado requires vehicles seven years old and older, registered in select counties, to have an emissions test every other year. These required counties are the most populated in the state. So, routine testing of vehicle carbon emissions is a necessity to ensure the air remains clean and breathable for all residents.

Required counties include:

  • Boulder
  • Denver
  • Broomfield
  • Douglas
  • Jefferson
  • Adams
  • Larimer
  • Weld
  • Arapahoe

As your new Nissan gets older, it might require more intricate repairs to ensure its hydrocarbon emissions remain low. That's where Larry H. Miller Nissan Highlands Ranch can help. Then, when it's time for your inspection, schedule an appointment with Air Care Colorado.

Routine Testing for Peace of Mind

If your Nissan comes due for emissions testing, you must schedule this test by the end of the month in which your current registration expires, according to the Colorado Department of Public Health and Environment. Even if your car, truck, or SUV is not due for emissions testing yet, you may schedule a general inspection for our technicians to perform to diagnose any future needs.

Air Care Colorado oversees CO state emissions testing and monitors vehicles for acceptable limits of hydrocarbons, carbon monoxide, or oxides of nitrogen. Please keep the following systems in mind as they will undergo inspection:

  • Onboard Diagnostics System (OBD)- "Check Engine" light
  • Catalytic converters
  • Air injection system
  • Oxygen sensors
  • Gas cap

If any of these components become faulty or go missing before your emissions test, you will have three business days to correct the issue. If repairs are needed, you can reach out to our service center for help.
