What is an obd2 emissions test?
An official OBD II emissions test consists of three parts: An inspector checks to see if the MIL light comes on when the key is turned on. If the light does not come on, the vehicle fails the bulb check. If the MIL light is on and there are any OBD II codes present, the vehicle fails the test and must be repaired.
Does Mass do emissions testing?
The most recent two model years of vehicles are exempt from emissions testing. Massachusetts—annually, as of 2008.
Does mass have emissions testing?
The Massachusetts Vehicle Check on-board diagnostic (OBD) emissions test is designed to ensure that the vehicle keeps running as cleanly as it was designed to run, which in turn protects the air we breathe. The OBD inspection test typically takes about 3 minutes.
How do you pass the OBD-2 emissions test?
To pass an OBD-II emissions test, a vehicle must: If you clear the ‘Check Engine’ light, or reset the OBD-II monitors right before your emissions test, your vehicle typically will not pass because the catalyst and EVAP monitors need time to run.
Why is an OBD inspection important in Massachusetts?
On-board diagnostics (OBD) inspections are an important part of the Massachusetts Vehicle Check Program. No one wants to drive a vehicle that is wasting fuel or polluting. An inefficient engine or emissions control system adds pollutants to the air in our region and reduces a vehicle’s fuel economy.
What is an on-board diagnostics ( OBD ) test?
1996 and newer model vehicles undergo an On-Board Diagnostics test, and a gas cap leak check instead of the traditional tailpipe and tampering test. On-Board Diagnostics tests significantly enhance the overall emissions reductions achievable by the vehicle emissions testing program. What is On-Board Diagnostics-II (OBD II)?
How is the OBD system used in the smog test?
Later, OBD smog test or the application of OBD system checks with OBD-I/M functionality was legalized. The primary OBD system could read, record and display error codes after monitoring the exhaust gases of each vehicle. Now, OBD systems have been expanded and are better equipped at monitoring and controlling vehicle emissions.
How long is the on-board diagnostic emissions test?
The on-board diagnostic emissions test (OBD) checks your vehicle’s computer communication system, Check Engine light, testing readiness, and engine and emissions control data, among others. The test takes a few minutes to complete.
On-board diagnostics (OBD) inspections are an important part of the Massachusetts Vehicle Check Program. No one wants to drive a vehicle that is wasting fuel or polluting. An inefficient engine or emissions control system adds pollutants to the air in our region and reduces a vehicle’s fuel economy.
Why do you need an OBD emissions test?
The OBD system pulls together data from a vehicles catalytic converter, misfiring cylinders, oxygen sensor, and coolants to make accurate measures of emissions. The catalytic converter is one of the most important components of emissions control. Because its main role is to clean exhaust gases.
What happens if you fail the emissions test in Massachusetts?
If a non-commercial vehicle fails its Massachusetts car emission test, the vehicle owner may be eligible for a Waiver of Emissions Standards for the smog portion of the test, but not the safety inspection. The smog test waiver remains valid until the vehicle’s next annual inspection.
