Front oxygen sensor rear oxygen sensor
The oxygen sensor in front of the three-way catalytic converter is called the front oxygen, and the rear oxygen is mounted after the three-way catalytic converter. It is generally considering that the front oxygen has a greater effect than the rear oxygen, because the front oxygen is used to adjust the density of the mixed gas, and the rear oxygen is to monitor the working condition of the three-way catalytic converter. Oxidation reaction will occur when the three-way catalytic converter is working, such as CO+02=CO2, which means that the oxygen content monitored by the rear oxygen is less than that of the front oxygen.  Otherwise, the three-way fails or the purification capacity decreases, a few vehicles will light up the fault light, prompting the owner to check or replace the catalyst.
lifespan of oxygen sensor :
100，000 kilometers is a small hurdle for a vehicle. A car that is not well maintained will enter frequent failures outbreak period. The oxygen sensor is a part that almost no one has thought of replacing., but it is the one that must be paid attention to and replaced Irregular. The main materials of the oxygen sensor are platinum and zirconium oxide. Its service life is generally 8-10 kilometers. There are three types of oxygen sensor failure modes: CO poisoning, sulfur and phosphorus poisoning, lead poisoning, silicon poisoning, and manganese poisoning. The quality of gasoline and lubricating oil has a great impact on the life of the oxygen sensor.
