The core material of these oxygen sensors are ZrO2 ceramics which has characteristic of high hardness but brittle. It can easily get damaged by physical hits. For example, dropping the sensor to ground will maintenance. In this case, the car engine fault light would light up.
Some of the newer models uses resistance to warm up sensor chip for speed up the operating. These resistance be easily burnt or melt in extreme situation. Which will than cause the oxygen sensor can't reach working temperature.
The exhaust gas could also cause contamination to oxygen sensor. There are mainly three types of contamination could happen: Silicon, Lead and Carbon. These compounds can accumulate and stick to the prob and limit air flow into and out to the sensor.
1. Industry certificate: IATF16949, CE;
2. Complete products, 99% of the world's models of oxygen sensors are produced, and there are more than 2,000 product models;
3. Master the core and check the quality from the source. The core components of the oxygen sensor, the zirconium tube and the chip core, are independently produced by our company, and the raw materials (zirconium powder, platinum paste, etc.) are imported raw materials, and adhere to the principle of quality first;
4. The inspection is fine, all products need to go through 100% inspection, the inspection items include: air tightness test, signal sensitivity test, engine simulation loading test, pressure test, salt spray test, etc., to ensure that each one is a high-quality product;
Contact the logistics company, provide the logistics order number, confirm and update the logistics information in time, and ensure that the goods are delivered to the customer in good condition;
Follow up the sales of goods and the follow-up needs of customers in a timely manner, and do a good job in after-sales service.
