The exhaust pipe of a car is equipped with two oxygen sensors, located in the front and rear positions, which are called front oxygen sensors and rear oxygen sensors. Although their functions are similar, they have different focuses. The front oxygen sensor is mainly responsible for monitoring the combustion efficiency of the engine and the oxygen content in the exhaust gas.
Advantages：
1. Accurate monitoring: accurate monitoring of oxygen sensors make complete engine combustion and stronger performance.
2. Anti-damage: NIBD oxygen sensor can long-term work or harsh environment without premature damage.
3. Circuit anti-failure: NIBD oxygen sensor circuit keep accurate data transmission and the monitoring effect.
