The sensors and actuators, along with the diagnostic computer software in the on-board computer, make up what is called "the OBD system".

CONT

By the early 1980s, numerous vehicles were using electronics and on-board computers to control many of the engine's control systems, such as fuel and ignition. Vehicle manufacturers had to develop ways to diagnose problems generated by the new electronic hardware found under the hood. Thus, the first OBD systems were developed by auto manufacturers in the early 1980s as electronic systems replaced mechanical systems.

OBS

[One of the main purposes] of the OBD system is to assure proper emission control system operation for the vehicle's lifetime by monitoring emission-related components and systems for deterioration and malfunction.
