All cars made after 1980 are equipped with an oxygen sensor, typically located within the emissions control system. This sensor communicates data to the engine's management computer, assisting in maintaining optimal engine performance.

It monitors oxygen levels in the exhaust gases and should be changed every 60,000 to 90,000 miles in your vehicle to guarantee proper functionality.
