The oxygen sensor indirectly reflects the concentration of the mixture into the cylinder, and this information is transmitted to the electronic control unit (ECU) by fluctuating voltage, so the main method to judge the performance of the oxygen sensor is to detect the signal voltage value of the output of the oxygen sensor and its fluctuation range and fluctuation frequency. On the other hand, the engine can only activate the oxygen sensor if it reaches a certain temperature.
Advantages:
1. Accuracy: NIBD oxygen sensor is high accuracy in the monitoring of the oxygen. High accuracy indicates good quality.
2. Material quality: Choose products with good material quality for better durability.
3. Brand reputation: NIBD brand products was insuranced by PICC with good reputation and credibility for better quality.
4.Certification: NIBD have passed the strict inspeciton by the ISO9001 international quality organization, and got the ISO9001 certificate.
