- Four wires serve two independent circuits - two for the internal heater and two for the sensor signal and ground
- Monitors oxygen content in exhaust gases and sends data to the engine control unit (ECU) to optimize air-fuel mixture
- Ensures proper emissions performance and fuel efficiency
- Specifically designed as the front (upstream) oxygen sensor, located before the catalytic converter
- On vehicles with dual exhaust, typically used on the passenger side
- Failed oxygen sensors may cause check engine lights, reduced efficiency, and higher emissions
