What to Do When BYD Tang's Tire Pressure Monitoring Suddenly Shows Abnormal Readings?
3 Answers
If the tire pressure monitoring system of your BYD Tang suddenly shows abnormal readings, you can enter the tire pressure sensor matching mode to re-match the tires for inspection. If the issue persists, it is recommended to directly consult your local dealer for inspection and repair. Below are the common causes of tire pressure faults and their solutions: Causes of Tire Pressure Faults: Illumination of the tire pressure monitoring light due to a punctured tire; sometimes, the light may come on due to excessively high tire pressure; prolonged driving with low tire pressure can also trigger the tire pressure monitoring light. Solutions for Tire Pressure Faults: Usually, it's a very slow leak, making it difficult to immediately identify which tire is affected. In such cases, you can use a tire pressure gauge to measure the pressure. The standard pressure is 2.3 bar for the front tires and 2.5 bar for the rear tires. If a tire is underinflated, inflate it to the correct pressure and then observe the tire pressure warning light. If the light comes on again after a few days, you may need to remove the tire for a thorough inspection. According to the international GBT2978-2008 standard, the recommended inflation pressure for passenger car tires is: standard tires: 2.4-2.5 bar; reinforced tires: 2.8-2.9 bar; maximum pressure: should not exceed 3.5 bar. If any tire exceeds 3.0 bar, it may trigger the tire pressure monitoring light. If a tire's pressure is too low, high-speed driving can cause the tire temperature to rise, leading to increased tire pressure. In such situations, you should promptly stop to rest or replace the tire with a spare.
Having driven for over a decade, encountering abnormal tire pressure monitoring in a BYD Tang isn’t new to me. When the alarm goes off, don’t slam on the brakes—gradually pull over. After stopping, first feel each tire by hand to check for obvious leaks or flatness. If nothing’s wrong, it might just be the sensor acting up. Try turning off the car and waiting ten minutes before restarting to let it reset automatically. Sometimes, mud or water on the wheels interferes with the signal, and a simple car wash can fix it. If there’s a real issue, like low pressure, visit a nearby repair shop for a tire top-up. BYD’s original sensors aren’t very durable and often need replacing after five or six years. Remember, low tire pressure on highways is risky, so regularly checking with a tire pressure gauge can save you trouble.
As a car tech enthusiast, I'm quite familiar with the tire pressure system of the BYD Tang. Abnormal alarms are usually caused by sensor battery depletion or signal interference. You can first check the tire pressure values displayed on the in-car screen; garbled data indicates sensor malfunction. Try turning off and restarting the engine or accessing the system menu to click the reset function; if it still doesn't work, you'll likely need to replace the sensor. Don't rush into DIY programming—getting a professional inspection at a 4S shop is more efficient. During regular maintenance, clean the wheel hubs to prevent rust buildup and extend their lifespan; keeping a wireless tire pressure gauge for self-testing is more reliable, helping to nip problems in the bud.
