• High-quality Materials: The oxygen sensor is a measuring element that uses ceramic-sensitive elements to measure the oxygen potential in various heating furnaces or pipes, to monitor and control the combustion air-fuel ratio in the furnace
• Installation Method 1. find the location of the oxygen sensor. the oxygen sensor is usually installed on the manifold or pipe. 2. disconnect the wiring harness plug of the oxygen sensor. 3. use a suitable tool to loosen the fixing screws of the oxygen sensor. 4. carefully remove the old oxygen sensor. 5. apply an appropriate amount of anti-seizing agent on the threads of the new oxygen sensor. 6. gently screw the new oxygen sensor into the mounting hole, being careful not to use excessive force to avoid damaging the threads. 7. tighten the fixing screws, but do not over-tighten to avoid damaging the sensor. 8. connect the wiring harness plug of the oxygen sensor
• Pre-shipment Check: We inspect each o2 sensor upstream before shipping to ensure it meets high-quality standards. Please check whether it suits your car model before purchasing. Please let us know if you have any questions, and we will provide a satisfying solution.
