Collection: Oxygen Sensors

Oxygen sensors, also known as O2 sensors, play a vital role in monitoring the oxygen levels in the exhaust gases of the vehicle's engine. Located in the exhaust system, typically before & after the catalytic converter, these sensors measure the amount of oxygen present in the exhaust stream. The information provided by the oxygen sensors is used by the engine control unit (ECU) to adjust the air-fuel mixture for optimal combustion efficiency & to monitor the effectiveness of the catalytic converter. Oxygen sensors can be of different types, such as heated or unheated, & they utilize a chemical reaction or electrical resistance to generate a voltage signal based on the oxygen content. A malfunctioning or worn-out oxygen sensor can result in various issues, including decreased fuel efficiency, increased emissions, & poor engine performance. Regular maintenance & timely replacement of faulty oxygen sensors are crucial for ensuring optimal engine operation & compliance with emissions regulations.
