To understand the tire pressure warning light and its significance, it’s essential to familiarize yourself with the functioning of Tire Pressure Monitoring Systems (TPMS). There are two main types of TPMS: direct TPMS and indirect TPMS.
Direct TPMS
Direct TPMS relies on pressure sensors and transmitters installed inside each tire or wheel assembly to monitor tire pressure. These sensors continuously measure the air pressure and send the information to a receiver within the vehicle’s onboard computer system. When a tire’s pressure drops 25% below the recommended level, a low-pressure signal is triggered, illuminating the tire pressure warning light on the dashboard and often accompanied by an audible alert.
The direct TPMS provides accurate and real-time tire pressure readings for each individual tire, allowing drivers to monitor and maintain optimal tire inflation levels. This system is commonly found in newer vehicles and offers precise monitoring, ensuring that any significant pressure loss is promptly detected.
Indirect TPMS
Indirect TPMS, on the other hand, utilizes the wheel speed sensors of the vehicle’s anti-lock braking system (ABS) to indirectly determine changes in tire size due to pressure loss. The system continuously monitors the rotational speed of each wheel. If it detects a significant change that indicates a pressure loss of 25% or more, it triggers the tire pressure warning light and may also sound an alert in the vehicle (RepairPal).
Indirect TPMS does not rely on individual pressure sensors within the tires. Instead, it utilizes existing sensors to detect discrepancies in rotational speed among the tires. When one tire’s diameter changes due to pressure loss, it affects the rotational speed compared to the other tires, signaling a potential problem.
Both direct and indirect TPMS systems play a crucial role in monitoring tire pressure and alerting drivers to any issues. Regularly checking your tire pressure using a tire pressure gauge is still recommended to ensure accurate readings and proper maintenance.
Understanding how TPMS works can help you respond appropriately to the tire pressure warning light and take necessary actions to address any issues promptly.
