The oxygen sensor, often abbreviated as the O2 sensor, plays a pivotal role in the optimal functioning of a vehicle. It’s a small component, often unnoticed but playing a crucial part in managing the car’s engine performance and emissions.
This sensor resides within your vehicle’s exhaust system and is primarily responsible for tracking the amount of unburnt oxygen present in the exhaust. It feeds this data back to the engine control unit (ECU), which utilizes this information to adjust the air-fuel mixture entering the engine. This process ensures efficient combustion, leading to better fuel economy and lower emissions.
