When does tire pressure monitoring system light up?
Typically, a Tire Pressure Monitoring System (TPMS) will illuminate. It happens should the tire pressure drop. It will precisely light up if the pressure drops 25% below the required value. In our case, the TPMS may be issuing false signals. What can you do? There are some situations whereby the tires are not underinflated or flat.
What causes the TPMS warning light to go on?
In Cold Weather: Colder weather causes the tire air pressure to drop. If the pressure goes below the threshold for your TPMS, the dashboard warning light will go on.
