What to Do When the Tire Pressure Monitoring Sensor Runs Out of Battery?
2 Answers
Tire pressure monitoring sensor runs out of battery can be replaced at a 4S shop. The battery life of tire pressure monitoring sensors is relatively long, generally lasting 4 to 6 years. The installation locations of tire pressure monitoring sensors include: 1. Built-in tire pressure monitoring: installed inside the tire, replacing the original valve; 2. External tire pressure monitoring: installed outside the valve. The functions of tire pressure monitoring are: 1. It will promptly alarm when there is rapid or slow air leakage due to a nail puncture; 2. It will alarm when tire loosening causes unbalanced friction, leading to tire temperature reaching 70 degrees Celsius to prevent tire blowout; 3. It will alarm when the tire has not been inflated for a long time and the pressure falls below the vehicle's set limit, preventing low pressure from causing tire temperature rise and blowout.
I've encountered the issue of tire pressure sensor battery depletion several times. It's usually due to the internal small battery running out, which typically lasts about five to ten years. If you notice the tire pressure warning light on the dashboard staying on or flashing erratically, there's a high chance the sensor is malfunctioning. Don't panic—first, try restarting the car to see if it resets, though this rarely works. I recommend heading to a professional repair shop immediately for a check-up. The mechanic will use a diagnostic tool to identify which wheel's sensor has failed and then replace it outright. Replacing one usually costs around 100 to 300 RMB, including parts and labor—a bit pricey, but safety comes first. If you delay the replacement, you might not even notice a tire leak while driving on the highway, which is extremely dangerous. During routine maintenance, checking the sensor's battery level can help prevent this issue and reduce potential risks.
