Your Mini Cooper may indeed represent the pinnacle of economy in a non-hybrid car. Like any car, the Mini Cooper operates at its best within ideal parameters. This requires periodic maintenance, performed on a schedule as recommended by the manufacturer.

The Mini Cooper Oxygen Sensor Key is to engine performance and efficiency. For the engine to run at its best while minimizing emissions, an idea balance of fuel and air is required.

The lowest emissions result from a leaner fuel-air mixture - in other words, a higher ratio of air to fuel. The Mini Cooper Oxygen Sensor detects oxygen amounts in the exhaust, then delivers this data in the form of electronic signals to the fuel-injection system. The vehicle must be at running temperature for an oxygen sensor to operate properly, so signals are not delivered to the fuel injectors until the engine has reached operating temperature. When the oxygen sensor fails to operate properly, the result can be poor performance, increased fuel consumption, and foul smelling exhaust.
