O2 Sensor (Oxygen Sensor)
An Oxygen Sensor (O2 Sensor) is a critical component in modern automotive engines that monitors the amount of oxygen present in the exhaust gases. The sensor sends real-time data to the Engine Control Unit (ECU), helping optimize the air-fuel mixture for better fuel efficiency, engine performance, and reduced emissions.
Key Functions of an O2 Sensor
✅ Monitors oxygen levels in exhaust gases
✅ Optimizes air-fuel ratio
✅ Improves fuel efficiency
✅ Reduces harmful emissions
✅ Supports engine performance
✅ Helps maintain environmental compliance
