Quick links: Test Day Tips | Adobe Acrobat Reader

The Tinley Park station provides service to the south suburbs of Chicago.  This brand new "OBD only" emissions testing station is located at 7460 W. Duvan Drive in Tinley Park. “OBD only” stations can perform emissions tests on vehicles equipped with an on-board computer.  Most vehicles that are model year 1996 and newer can be tested at Tinley Park. Due to the high volume of testing occurring at many of the older stations, such as the Markham station, Tinley Park may be a faster and convenient alternative for many local residents. Currently, the Tinley Park station is experiencing short wait times, and with no appointments necessary, drivers can get on their way faster.

Tips for a successful test:

• Please bring your vehicle to an Air Team test station as soon as possible after receiving your test notice.  If your vehicle is rejected or fails the inspection, this will provide ample time to repair the vehicle and have it re-inspected prior to license plate expiration.
• Test stations are closed on Sundays and state holidays.  The busiest testing day is Saturday.

• Please bring your vehicle's test notice with you to the test station. 
• Make sure the vehicle brought in for testing matches the vehicle identified on the test notice.
• Please drive your vehicle for at least 15 minutes prior to entering the test station to ensure that your vehicle is adequately warmed-up for the inspection. 
• If your 1996 or newer OBD-equipped vehicle has a covered or otherwise obstructed diagnostic link connector (DLC), please open or remove the cover (consult owner's manual for location and instructions), or remove the obstruction prior to arriving at the test station.
• If your 1996 or newer OBD-equipped vehicle has recently been serviced, or if the battery has been disconnected, please drive the vehicle for several days before bringing it in for inspection.
• Make sure your gas cap is present. If your gas cap locks, bring the key with you.
• Ensure your vehicle is safe to operate. Your vehicle may be rejected if the test cannot be safely conducted.

• When you arrive, leave the engine running unless directed otherwise.
• Inform the inspector when entering the test lane if the license plate number on the vehicle is different from the number on your test notice.
