Where Air Team is located and what they test

Air Team operates a vehicle emissions testing station in Schaumburg at 1850 North Rand Road, Suite 100. They perform the OBD (on-board diagnostic) emissions test that Illinois requires for most vehicles registered in Cook County. This is the test that reads your vehicle's computer to check whether your emissions systems are working correctly.

Air Team tests gasoline-powered vehicles, diesel vehicles, and hybrid vehicles. They do not test motorcycles or vehicles registered outside Illinois. The test takes about 10 to 15 minutes and costs $30 (as of the most recent published rate, though you should confirm the current price when you call or visit).

What documents and vehicle condition you need before you go

Bring your vehicle registration and a valid photo ID (driver's license, passport, or state ID). The registration must match the vehicle you are testing. If you are testing a vehicle registered to someone else, bring a notarized power of attorney or have the registered owner present.

Your vehicle's check engine light must be off. If the light is on, Air Team will not perform the test because the vehicle has already triggered a diagnostic code. You will need to have the vehicle scanned and repaired first, then return for testing. Your vehicle also needs to have been driven for at least 20 minutes before the test so the engine reaches operating temperature — this is a technical requirement of the OBD test itself.

How the test works and what happens if you fail

During the test, Air Team connects a diagnostic scanner to your vehicle's OBD port (usually located under the steering wheel or dashboard). The scanner reads the emissions-related codes stored in your vehicle's computer. The test does not involve a tailpipe emissions measurement — it only checks whether your emissions control systems are functioning as designed.

If you pass, you receive a passing certificate on the spot. This certificate is valid for two years and satisfies Illinois's emissions testing requirement for vehicle registration renewal. If you fail, Air Team will tell you which emissions system is not working correctly. You then have 30 days to have the vehicle repaired and return for a retest. The retest is free if you return within 30 days of the original test date.

Hours, contact information, and what to do if you cannot visit in person

Air Team's Schaumburg location is open Monday through Friday. Specific hours vary, so call ahead at the station directly or check their website to confirm current hours before you drive there. They do not test on weekends or major holidays.

If you cannot visit the Schaumburg location, Air Team operates other testing stations throughout Cook County. You can search for other locations on the Illinois Secretary of State's website, which maintains a list of all licensed emissions testing stations. You do not have to test at the same station twice — if you fail and prefer a different location, you can return to any licensed station for your retest.

What your passing certificate covers and how long it lasts

A passing emissions certificate from Air Team is valid for two years from the test date. You will need this certificate to renew your vehicle registration with the Illinois Secretary of State. When you renew your registration online, by mail, or in person at a Secretary of State facility, you will be asked whether your vehicle has passed emissions testing. Present or reference your certificate.

The certificate covers only the emissions test itself. It does not cover vehicle safety inspection, which is a separate requirement in some Illinois counties. Check with your local Secretary of State office or your vehicle registration renewal notice to see whether you also need a safety inspection.

What to do if you fail and need to understand the repair codes

When you fail the emissions test, Air Team will provide you with the specific diagnostic trouble code (DTC) that triggered the failure. This code is a four-character alphanumeric string (for example, P0420 or P0171) that identifies which emissions system is not working. Write down this code.

Take this code to a mechanic or repair shop. The mechanic can look up what the code means and what repairs are typically needed to fix it. Some repairs are straightforward and inexpensive (a loose gas cap, for example), while others may require more involved work. Once the repair is complete, return to Air Team within 30 days for your free retest. You do not need the original Air Team paperwork — just bring your registration and ID again.

Frequently Asked Questions

Can I test a vehicle that is not registered in my name?

Yes, but you will need either a notarized power of attorney from the registered owner or the owner present in person with their ID. Air Team must verify that someone with authority over the vehicle is requesting the test.

What if my vehicle has a pending repair and the check engine light is still on?

You cannot test until the light is off. Have the vehicle scanned and repaired first, then clear the code (or have the mechanic clear it). The light must be off for at least one full drive cycle before you return to test.

Do I need an appointment, or can I just walk in?

Air Team accepts walk-ins, but calling ahead is a good idea to confirm they are not backed up. Wait times vary depending on the time of day and day of the week. Early morning or mid-week visits are often faster.

What if I pass the test but my registration renewal notice says I still need emissions testing?

This usually means the test was not yet recorded in the Illinois Secretary of State's system. Wait a few business days for the results to upload, then check your renewal status online. If it still shows as needed after a week, contact Air Team with your test date and certificate number to confirm the results were submitted.

Can I test a vehicle with a temporary registration or out-of-state plates?

No. Your vehicle must have a current Illinois registration. Temporary registrations and out-of-state plates do not meet the requirement. Once you have a permanent Illinois registration, you can test.
