Licensed inspection stations use (NYVIP3) equipment to monitor the on-board diagnostic system (OBDII) of your vehicle. 1 If the OBDII detects a problem that can result in excessive emissions, a malfunction indicator light (MIL) illuminates to inform the driver or automotive technician.

What is OBDII and how does it work? [Back to Top]
The first on-board diagnostic (OBD) systems were introduced in the early 1980's to lower vehicle emissions and help automotive repair technicians in the diagnostics and repair of computerized engine controls. As a results of improved technology, a new generation of OBD (OBDII) was developed for 1996 and newer vehicles. The new OBDII systems monitor the vehicle's electronic sensors and actuators while the vehicle is being driven to insure they are working "as designed" by the manufacturer. The on-board computer has the ability to identify a problem well before the driver is aware of any problems, such as lack of performance, high emissions, or poor fuel economy. Early detection helps avoid costly repairs and can improve the vehicle's emissions.

Note for model year 1996 and newer vehicles: When the Check Engine light is illuminated on your dashboard, then (in the vast majority of cases) your car will not pass DEQ and is in need of repair. Once your vehicle receives repair and the Check Engine light has turned off, be sure your mechanic explains the drive cycles your vehicle must experience prior to going through DEQ's test. Otherwise, if you test too early after a repair your test results will be Unready," meaning your vehicle's computer hasn't finished evaluating all of the emission control equipment.
