 OBDQA - Massachusetts Enhanced Emissions and Safety Test
OBD is your vehicle's on-board diagnostic computer, which continuously monitors the engine, transmission, and emissions control system and serves as an "early warning system" that can reduce air pollution and save you money.
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.
OBD stands for "on-board diagnostics." Most 1996 or newer vehicles have standardized computer systems and sensors that monitor the performance of their engines and emissions control systems.

 Frequent Questions - On-Board Diagnostics - OTAQ - EPA
OBD and tailpipe testing are two different approaches to identify vehicles in need of repair.
Because of its ability to monitor individual components, OBD is able to give motorists an "early warning" that repairs are needed; it is because of this "early warning" capability that OBD will sometimes fail vehicles that would otherwise pass a tailpipe test.
OBD helps to ensure these vehicles are running in top shape, but you still need to maintain your vehicle according to the manufacturer's recommended schedule.

 Have You Heard About OBD III?
As the OBD II (federal OBD uses the same basic technical standards as California OBD II) debate comes to a close, speculation is already mounting about an OBD III concept in California.

 On Board Diagnostics - Wikipedia, the free encyclopedia
Modern OBD implementations use a standardized fast digital communications port to provide myriad realtime data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow one to rapidly identify and remedy malfunctions within the vehicle.
Unlike the OBD-I connector, which was sometimes found under the hood of the vehicle, the OBD-II connector is always located on the driver's side of the passenger compartment near the center console.
OBD scan tools can be categorized in two ways, based on whether they require a computer to operate (stand-alone vs PC-based), and the intended market (professional or hobby/consumer use).

 State of Delaware Division of Motor Vehicles
OBD is short for "On-Board-Diagnostic" and simply refers to those systems that are controlled or incorporated into the new automobile computers to monitor or control systems that affect the vehicle emissions.
OBD II turns the MIL on when a failure occurs which could cause vehicle emissions to exceed 1.5 times their designed standard.
To help ensure the OBD system is working properly, “readiness codes” are used to indicate whether or not monitored emissions control systems have been tested by the OBD system.

 Understanding On-Board Diagnostics
The purpose of the OBD system is to ensure proper emission control system operation for the life of the vehicle by monitoring emissions related components and systems for deterioration and malfunction.
These monitors are included in the OBD system so overall vehicle condition can be easily assessed electronically at an emissions test station, using a data link connected to the vehicle.
After a vehicle fails an OBD test where any of the fault codes are for catalyst efficiency, the catalyst monitor must be “ready” prior to a re-test.

 OBD II Explained
OBD II is a federally mandated engine and emissions management standard for all passenger cars sold in 1996 and beyond.
OBD II upgrades this snooping to things like converter efficiency, engine misfire, even electrical integrity of idle air controllers, throttle-position sensors and transmission actuators.
But OBD II takes this sensor's input, analyzes it and recognizes the minute fluctuations that are concurrent with engine misfire.

 OBD II - 2000 and Beyond
OBD II is different from OBD I in that OBD II is strictly emissions oriented — it will illuminate the malfunction indicator lamp (MIL) whenever it detects a component/system malfunction that could cause emissions to exceed 1.5 times the federal test procedure (FTP) standards for that model year of vehicle.
OBD II is constantly monitoring itself for opens, shorts, out-of-range values, component integrity, functionality and faults that could cause an increase in tailpipe emissions more than 1.5 times the FTP standard.
For regular-mileage vehicles, OBD II DTCs identified system or component problems that were in need of repair or that could have eventually resulted in high emissions 94 percent of the time (30 of 32 vehicles).

 OBD II EQUIPMENT QUESTIONS (10/18/01)
The OBD II failure parameters include other considerations in addition to the 1½ times the applicable FTP standard requirement.
  While some have promoted the OBD II system as an “emissions light”, the system is really a control system light, indicating when problems have cropped up in the vehicle’s engine control system.
By the way, this issue is something of a “red-herring”, or non-issue, since OBD II vehicles rarely come into a repair facility with more than two or three codes in the data stream.

The OBD-I systems were required to monitor all inputs for a high / low range, the EGR system, the oxygen (O2) sensor, the fuel metering system, and the engine control module (ECM).
The OBD-I regulations were relatively easy for most manufacturers to comply with since most manufacturers were already monitoring these systems.
At the same time the OBD-I regulations went into effect, the standards for a second generation on-board diagnostic system (OBD-II) were released.
