How often does the modern Elantra oxygen sensor change? Positioning and replacement process of elantra oxygen sensor.

Under normal circumstances, the 2022 Elantra will have two oxygen sensors, namely the front oxygen sensor and the rear oxygen sensor. The front oxygen is generally in front of the three-way catalyst, and the rear oxygen is behind it. As shown in the figure below. 1 wiper water 2 battery 3 throttle 4 oxygen sensor 5 brake oil pot 6 fuse box 7 air filter 8 coolant pot oxygen sensor works in high temperature environment and needs to be replaced every 65438+ 10,000 kilometers. By observing the tip of the oxygen sensor, we can know whether it is necessary to clean the oxygen sensor. If the tip is black (mainly caused by carbon deposition), the sensor should be quickly removed and cleaned, and then 5- 10% ferric chloride solution and excess hydrochloric acid should be prepared. But if it is white or brown, it means that the oxygen sensor is poisoned. Cleaning it at this time is ineffective and needs to be replaced in time. Elantra oxygen sensor replacement tutorial 1, first determine the position of the oxygen sensor; 2. Remove the protective cover of the oxygen sensor plug and disconnect the oxygen sensor connector; 3. Remove the oxygen sensor with a special socket wrench; 4. Install a new oxygen sensor according to the original position; 5. Connect the trip computer, clear the fault code, and choose to read the engine data stream to check whether the values are normal.
