How to Deal with a Faulty Tire Pressure Monitoring System?
2 Answers
The methods to handle a faulty tire pressure monitoring system are: 1. Display the tire pressure and temperature readings on the dashboard and check for any abnormalities; 2. Inspect the underinflated tire for any leaks; 3. Examine whether the tire pressure monitor is malfunctioning. The causes of a faulty tire pressure monitoring system include: 1. A punctured tire; 2. Prolonged driving or failure to replenish tire pressure in time; 3. Malfunction of the tire pressure sensor; 4. Failure to reset the tire pressure module after tire replacement or repair. The functions of the tire pressure monitoring system are: to prevent accidents, extend tire lifespan, and reduce wear on the suspension system.
During my last road trip, the tire pressure warning light suddenly started flashing. I immediately pulled over to a safe area and checked each tire one by one. Turns out the right rear tire had a nail causing a slow leak. After putting on the spare tire, I drove to a repair shop where it cost me 20 yuan to fix it. Actually, in most cases, it's just a nail puncture causing air loss - I recommend keeping a portable air pump for emergencies. If the warning light comes back a couple days after inflating, it's probably just the sensor battery dying - replacing a new sensor costs around a hundred yuan. Remember to ask the technician to reset the TPMS after tire repairs, otherwise the warning light will stay on. With hot weather increasing blowout risks now, weekly tire pressure checks are essential.
