How to Determine if a Car's Oxygen Sensor is Damaged?
1 Answers
Here are the methods and precautions for determining if a car's oxygen sensor is damaged: 1. You can judge by observing the appearance color of the oxygen sensor. The normal tip color is light gray. If it is white or brown, it indicates damage, and the car's oxygen sensor must be replaced at this time. 2. When driving normally, try to keep it as smooth as possible. Unless it's an emergency or poor road conditions, try to minimize violent shaking and impacts on the car body, and also avoid scraping the undercarriage (especially near the tailpipe). 3. Pay attention to the sensor wire. During regular vehicle maintenance, be careful not to pull the wires excessively. Like other electronic devices, if the wire connections are unreliable, it will affect the normal operation of the oxygen sensor. 4. Be cautious with the tailpipe when washing the car after turning off the engine. Because the exhaust pipe of the tailpipe gets very hot during use, if the tailpipe is accidentally rinsed during car washing, the exhaust pipe may cool down rapidly due to external influences, which could cause the ceramic sensitive element of the oxygen sensor to crack. 5. Develop a habit of checking every 30,000 kilometers. It's best to inspect the oxygen sensor every 30,000 kilometers of vehicle use. If the sensor shows signs of aging or has already failed, clean it immediately or replace it with a new one.
