• In the context of exhaust systems, monitors the oxygen content of the exhaust gases

• Sends a signal to the engine control unit to regulate the air-fuel ratio

Most modern cars feature two oxygen sensors. The first is placed before the catalytic converter and measures the levels of oxygen and pollutants after combustion. The second sensor is then located after the catalytic converter to measure the pollutants being filtered through it. By monitoring and optimizing fuel efficiency, the oxygen sensor plays a vital role in maintaining the overall performance of your car’s exhaust system.

Catalytic Converter

The catalytic converter is a vital component of the exhaust system that takes the form of a smaller and slimmer muffler. It is composed of ceramic blocks or beads coated with precious metals such as platinum, which enable a series of chemical reactions and processes to reduce hazardous pollutants from exhaust gases.

Legally, every vehicle must have a catalytic converter installed to lessen the emission of harmful substances like nitrogen oxides, carbon monoxide, and unburnt hydrocarbons.

A properly functioning catalytic converter that meets legal requirements is key to reducing harmful emissions and upholding your vehicle’s performance.
