What does TPWS malfunction mean?
2 Answers
The TPWS malfunction on your vehicle indicates that the tire pressure needs calibration. Below are specific details about adjusting car tire pressure: 1. Rough roads: On roads with significant bumps, it's advisable to slightly reduce the tire pressure by 0.1-0.2bar below the standard tire pressure. For long-distance highway driving, tire pressure should not be too low; it's recommended to increase the pressure by approximately 0.2bar above the standard's lower limit. 2. Tire condition: For new tires, the pressure can be set about 0.2bar higher than the standard. For old tires, adjust the pressure slightly lower than the standard, and if the wear is severe, set it to the lower limit of the standard tire pressure. 3. Seasonal adjustments: In winter, it's generally advisable to increase the tire pressure by about 0.2bar above the standard. In summer, set the pressure to the lower limit of the standard. If the car is parked outdoors in summer, the pressure can usually be about 0.1bar lower than the standard to prevent blowouts due to high temperatures.
A TPWS fault indicates an issue with the Tire Pressure Warning System. Whenever this warning light comes on during my long-distance drives, I become extra vigilant. It means the system can't properly monitor the tire pressure status, mainly due to possible sensor battery depletion or moisture damage to the wheel hub equipment. I once experienced this on the highway when the light suddenly flashed—tire pressure was normal upon checking, but it turned out to be a short-circuited sensor from rainy conditions. Untreated, incorrect tire pressure significantly increases the risk of a blowout and also wastes fuel. I recommend stopping immediately to inspect or seeking professional diagnosis. Additionally, regularly checking tire pressure with a portable pump can prevent such issues—a habit I believe every car owner should adopt to ensure safe and smooth journeys.
