## Description

All cars that were manufactured post-1980 feature an oxygen sensor. It  is located within the emissions control system. When functioning, the O2  sensor sends data to the management computer located within the engine.  In your car, a functioning O2 sensor ensures that your engine is  running at top performance. Additionally, this sensor keeps your  emissions in check and alerts you to when emissions are too excessive.  For states that have vehicle inspection programs to regulate emissions,  the use of the CEL and O2 light will alert officials to any excessive emissions.
