The oxygen sensor of your car is responsible for the reduction of harmful exhausts emitted in the environment. It also ensures that the power trains are performing its duty efficiently by supplying the balanced amount of air content in the mixture. The combination of fuel and air goes through several complex processes to ensure that the balanced amount is given for the components making up the car. Oxygen sensors are usually positioned in the exhaust manifold in between the catalytic converter and the turbo for easier facility of the exhaust that must be emitted in the open.

Toning down the amount of harmful exhaust is done by the oxygen sensor by adjusting the amount of oxygen content in the much needed fuel and air mixture. It sends the signal to the ECM or computer system of the car, the component responsible for the adjustment of the fuel grade and the change in altitude of the amount of oxygen to be supplied and transported to the other auto parts comprising the vehicle. The harmful exhausts commonly given off by the car are nitrogen oxides, carbon monoxide and unburned hydrocarbons.

Cars meant for tough driving applications such as off road driving must be matched with durable and efficient oxygen sensor or O2 especially if the power supply is generated from fuel injected engines. It is commonly made from a ceramic body with platinum on the sides and a metal casing on the tip. The outside surface is covered with a ceramic coating which is in contact with the oxygen content in the car's exhaust system while the interior is open to the oxygen in the atmosphere.

Highly efficient oxygen sensors can enhance the over all capacity and handling dynamics of the car. It also means less harmful gas exhaust that can cause negative effects in our environment.
