When the TPMS light beams, what is it telling you? Read on to explore.

1. What TPMS means

TPMS stands for Tire Pressure Monitoring System which is a system that warns about a threatening change in the air pressure. The alert comes from a pressure sensing transmitters set inside the tires. These transmitters then send the alert to a central computer (ECU) to be displayed on the instrument panel. If a drop of more than 25% occured in tire pressure, a TPMS Warning Light will come on the panel and a notifying sound will come out.

When the TPMS illuminates and stays on, there are two possibilities:

1. One or more of your tires are at low level of pressure.

2. The TPMS transmitter is malfunctioning.

1. TPMS Light flickers and then keep staying on

In case the light goes on and off for a period of approximately 60-90 seconds and after you start the engine, it keeps illuminating, you should bring your car to an auto service center to check because it’s high chance the TPMS is out of order.

2. TPMS turns on and off

This happens when your tire pressure is on the brink of hitting the alert level and the temperatures change quickly. For example, the TPMS light may be on at night when the temperature reduces along with the pressure. However, the light will be inactivated when the coming of the day pulls up the pressure and temperature. Make sure to check the pressure of all the tire to diagnose which one need pumping up.
