The function and purpose of Oxygen Sensor.

Achieving maximum power and fuel efficiency with your car or truck depends on how well you maintain your engine and exhaust parts. The fuel-injection system on your Mercedes-Benz 420SEL is runs on signals sent by your ECU which relies on input from the oxygen sensors. Your Mercedes-Benz 420SEL oxygen sensors sit in the exhaust manifold, exhaust pipes, and catalytic converter and analyze the quality of the exhaust gases to determine how well your fuel delivery and emissions reduction parts are working. When oxygen sensors fail your car will not get the best fuel economy or produce enough horsepower, and it will likely be emitting an excess of hazardous exhaust.
