as long as you are not throwing a cel, you will pass.What is the OBD test and how does it work?
Massachusetts is now using an advanced computerized emissions test - the On-Board Diagnostics (OBD) test - for most model year 1996 and newer cars, light trucks, and SUVs The OBD emissions test is designed to ensure that your vehicle keeps running as cleanly as it was designed to run, which in turn protects the air we breathe.
The OBD test is quick and easy. The inspector connects your vehicle's on-board computer to a computer in the station, and then downloads engine and emissions control data. The results are printed on the Vehicle Inspection Report (VIR), which the inspector will give you when the inspection is finished.
If your vehicle passes both the OBD test and safety inspection, it is issued a sticker. If OBD detects a problem with your vehicle (generally indicated in advance by an illuminated "Check Engine" or "Service Soon" light), your vehicle will fail its inspection and will need to be repaired.
