TPMS sensors help

Do you know what to do when the low tire pressure TPMS symbol illuminates? The first thing 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, not on the sidewall of the tire- that’s the tire’s maximum pressure.) Keep in mind, your TPMS does not replace routine tire pressure maintenance. It’s a tool that can help alert you when pressure is low, but a tire may drop below proper inflation long before the TPMS warning light comes on. The TPMS light comes on when the tire pressure gets too low or too high.

When the TPMS light comes on – and stays on – at least one of your tires is at a low pressure level. Check the pressure of all of the tires with a gauge and determine the cause of pressure loss and add air or service the tire(s) as appropriate.

When tire pressure(s) are near the level that triggers an alert, fluctuating temperatures may be causing your TPMS light to turn on and off. This typically occurs when pressure decreases over night due to a drop in ambient temperature that causes the light to turn on; the light may turn off when pressure increases during the day due to rising ambient temperature and/or heat generated from the driving the vehicle. Use a gauge to check the pressure of all of the tires and add air to any tire that is low

TPMS light flashes and then stays on

If the light flashes for approximately 60 to 90 seconds every time you start your car and then remains illuminated, this means the TPMS isn’t functioning properly and you should take it to an automotive service center for an inspection or possible replace required.
