Structural Features
• The main sensitive material of the oxygen sensor is a zirconia. • The zirconia is activated by exhaust heating (300℃) ,then the oxygen ions through the zirconia components to reach their external electrodes. Zirconia components induct the oxygen content in the engine exhaust and change the output voltage.

Zirconia Oxygen Sensor Manual Outline
• Type:zirconia sensor. • OEM NO. :39210 22610 • Certificate:TS16949 / ISO 9001
Working Principle
• The oxygen sensor is an important part of the closedloop fuel control system. It aims to adjust and maintain the desired air-fuel ratio so that it helps catalytic converters to achieve the best conversion efficiency. When the engine combustion air-fuel ratio becomes small, the oxygen content in the exhaust increasing, oxygen sensor output voltage reduced.Otherwise the output voltage increased.By this way to feedback the airfuel ratio situation to the ECU.

Installation And Removal
IV. Re-install the sensor: use the right assembly adhesives coated thread. (Note: Do not let assembly adhesives touch the protective tube). Install a new sensor: we have coated the grease on the mounting thread and equipped with a protective sleeve. Do not remove the protective sleeve until you install the sensor.
Maintenance And Repair
• For engine oil, not oil more than the highest mark level on the dipstick. • Strict compliance with the testing and replacement cycle: should periodically (every 30,000 km) detect the oxygen sensor and the proposed cycle in accordance with our replacement.
Installation And Removal
I. In the operation of the oxygen sensor, it is recommended troubleshooting instructions related to the auto model. Assembly tools: use 22mm opening fixed wrench or adjustable wrench. Tightening torque: 40 ~ 60Nm (torque wrench).
Maintenance And Repair
Do follow to protect the oxygen sensor • Only use unleaded fuel without additives. • Regular maintenance and detection to the automobile • When Engine can not start, you can only use jumper cables to start. Not promote car to start, or the nonburning fuel will come into the exhaust system..
Failure Judgment
Note: All of the following judgment, based on the vehicle, harness, and other system components function properly. • Find system diagnostics fault by diagnostic equipment • Too little times of transitions between Concentrated dilute, heavy metals (such as: lead and manganese, etc.), phosphorus and sulfur poisoning, or high temperature damage.
