What To Do When Your Tpms Warning Light On?

When the TPMS symbol illuminates, the thing you most likely need to do is manually check your tire pressures with a gauge and add air until the pressures reach the vehicle manufacturer specification. (You’ll find the correct pressure on the driver’s door jamb or in the owner’s manual). There would be different kinds of TPMS warning light. Here comes 3 kinds of TPMS signals and the underlying causes of these signals:

1. If your TPMS light comes on, and stays on, that means at least one of your tires is at low pressure level. After knowing that, you should check the pressure of all of the tires with a gauge and add air or service the tire(s) accordingly.

2. If TPMS light goes on and off, it could be caused by fluctuating temperatures in tire. Normally temperature during day would higher than night, ambient temperature would influence temperatures in tire and as a result affect the tire pressure. Tire pressure decreases overnight due to a temperature drop in tire, thus TPMS light triggers an alert and was turned on; During the day, the light may turn off when pressure increases due to rising temperature or heat generated from the driving the vehicle. This could be repaired by checking the pressure of all of the tires and add air to any tire that is low.

3. If the light flashes for approximately 60 to 90 seconds every time you start your car and then the light stays on, this is the signal of TPMS isn’t functioning properly, you should turn to an automotive service center for an inspection. To fix the problem, you need to replace a new TPMS in most cases.
