Understanding the Tire Pressure Monitoring System (TPMS)

The TPMS is a safety feature designed to monitor the air pressure inside your tires. Sensors within each tire transmit data to the car’s computer, alerting you when the pressure drops below a certain threshold, typically 25% below the recommended pressure. This early warning system helps prevent accidents caused by underinflated tires, which can lead to reduced fuel efficiency, decreased handling, and increased tire wear.

The system in your 2019 Corolla consists of sensors in each wheel, a receiver, and the warning light on your dashboard. When a sensor detects low pressure, it sends a signal to the receiver, which then triggers the light. However, sometimes the system needs to be reset after you’ve corrected the tire pressure or after rotating your tires. Understanding how to properly reset the TPMS will ensure you receive accurate warnings and maintain optimal tire performance.

Why the Light Stays On After Inflation

Several factors can cause the tire pressure light to remain illuminated even after inflating your tires to the recommended pressure, which is typically found on a sticker located on the driver’s side doorjamb. One common reason is that the system hasn’t had enough time to recalibrate. It might take a few miles of driving for the sensors to transmit the updated pressure readings to the car’s computer.

Another potential cause is a faulty sensor. If a sensor is damaged or has a dead battery, it won’t be able to accurately transmit pressure readings. Extreme temperatures can also affect the accuracy of the sensors, causing the light to flicker on and off. Finally, if you’ve recently rotated your tires, the system may need to be reset to recognize the new sensor locations.
