Oxygen Sensors - 11787848486
Description
The downstream oxygen sensor, also known as the post-catalytic converter oxygen sensor, is a component in a vehicle's exhaust system. Its primary function is to monitor the level of oxygen in the exhaust gases after they have passed through the catalytic converter.
The catalytic converter is responsible for reducing harmful emissions by converting pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), and unburned hydrocarbons into less harmful substances like carbon dioxide (CO2), nitrogen, and water. The downstream oxygen sensor plays a crucial role in ensuring the efficiency of the catalytic converter.
Your vehicle's oxygen sensor works with your engine control unit to optimize your engine's performance. The oxygen sensor is measure the proportion of oxygen in the exhaust sends input back to the engine control unit so it can modify the vehicle's air fuel ratio based off of it's current conditions. In doing so your Oxygen Sensor is a major part of your vehicle engine management and fuel consumption.
