How to eliminate TPWS fault?
2 Answers
When a car displays a TPWS fault code, it means the tire pressure needs to be recalibrated. Here are the specific details: 1. Causes: When tire pressure is too high, the contact area between the tire and the ground decreases, increasing the pressure on the tire and reducing grip, which affects vehicle comfort and stability. When tire pressure is too low, the contact area with the ground increases, leading to greater tire deformation, accelerated tire wear, shortened tire lifespan, and even the risk of a blowout. 2. Solution: Vehicles with this fault code are equipped with a tire pressure monitoring system (TPMS). The TPMS continuously monitors the vehicle's tires in real time and immediately alerts the driver to underinflated or overinflated tires, ensuring safe driving.
As a seasoned driver with over a decade of experience, the first thing I do when the tire pressure warning light comes on is to pull over to a safe spot and check the pressure gauge. More often than not, it's just low tire pressure—simply inflate to the standard value, restart the car, and the light goes off. If it stays on, try resetting the system—refer to the owner's manual and follow the steps, like holding down the dashboard button for a few seconds. If that doesn't work, the sensor might be faulty, especially in cars five or six years old where the internal battery may be drained and need replacement. This is crucial because ignoring it could lead to hidden risks like blowouts on long trips or increased fuel consumption. Don't delay—drive to the repair shop on the weekend for a thorough check. Don't penny-pinch now only to pay more later; safety comes first. If you're DIY-inclined, parts are cheap, but you need some electrical know-how to avoid damage.
