Common Causes of the Tire Pressure Light
There are several common causes that can trigger the tire pressure light, including problems with the tire pressure monitoring system and using an unreliable tire pressure gauge. It’s important to understand these causes and address them promptly to ensure optimal tire pressure and safe driving.
One of the main causes of the tire pressure light coming on is a malfunction in the tire pressure monitoring system (TPMS). The TPMS uses sensors located in each tire to measure the pressure and sends a signal to the dashboard display or warning light if the pressure falls below the recommended level. However, these sensors can sometimes malfunction, leading to inaccurate readings and triggering the tire pressure light. If you suspect a TPMS malfunction, it’s best to have it checked by a mechanic to ensure proper functioning.
Another common cause of the tire pressure light is using an unreliable tire pressure gauge. It’s important to use a high-quality and accurate gauge to measure tire pressure. Using a cheap or faulty gauge can result in inaccurate readings, leading to incorrect tire pressure and triggering the tire pressure light.
