A New Oxygen Sensor Impacts Your Car!

A defective or sluggish oxygen sensor can cause a variety of issues, like decreased engine performance. Replacing a defective O2 sensor helps ensure your engine is constantly monitored and operating efficiently, while maximizing performance.	The ideal air-fuel ratio of a gasoline engine is 14.7 parts air to 1 part fuel, which is known as complete combustion. The vehicle's engine control unit uses an O2 sensor to regulate air-fuel mixture by checking the oxygen content in a vehicle’s exhaust. This results in fuel savings.	The catalytic converter is responsible for removing the harmful emissions from your vehicle’s exhaust. A defective oxygen sensor can cause your catalytic converter to fail prematurely. Replacing a catalytic converter can cost thousands of dollars, significantly more than most standard oxygen sensor replacements.	If complete combustion is not maintained, other chemical compounds can form in large amounts. These include greenhouse gases, carbon monoxide and excess hydrocarbons. Replacing a defective oxygen sensor is the most effective way to control the combustion process and reduce emissions.
