How to Reset Tire Pressure Light
You’ve inflated your tires to the right PSI, but your tire pressure light is still on. It happens sometimes, and you may need to reset it. Your tire pressure monitoring system (TPMS) is essential to the safety of your vehicle, and it’s important to ensure it’s activated. If you’re running into any problems when trying to figure out how to reset the TPMS light, follow these steps, or bring your vehicle to the service center at Sam Leman Toyota Bloomington.
Why is Your Tire Pressure Light On?
Your TPMS light could be on when your car starts up, or it could turn on while you’re driving. You could also have a flashing or blinking tire pressure light (more on that below). Whether your tire pressure light turns on while you’re driving around Bloomington or it lights up after you’ve started your car, it is usually because of:
Significant changes in weather or temperature: If the air pressure falls or the temperature drops suddenly, your tires will often follow suit. If you haven’t kept up with regular tire pressure checks, one or more tires might lose enough pressure to trigger the TPMS light.
A leak in one or more tires: If there’s no sudden weather changes, the most likely cause for the lost air pressure is a leak. While you can try to fill up the tire(s) with air, you’ll need to visit a service center to either patch the tire(s) or replace it.
What Does It Mean When the TPMS Light is Flashing?
The tire pressure sensors use a battery, and if the TPMS light is flashing, it could mean that the battery needs to be replaced. It could also indicate a problem with one of the sensors. Where is the tire pressure sensor located? It is inside the tire attached to the inner part of the rim. If you remove the tire from the rim, you’ll see a small cylinder, which is the tire pressure sensor.
If your TPMS light is flashing, you will want to schedule a service appointment as soon as possible at Sam Leman Toyota Bloomington. We can inspect your vehicle, diagnose the problem, and get you back on the road safely in a timely manner.
How to Reset Your Tire Pressure Light
Once you have properly inflated your tires, the tire pressure light should go off on its own. If it stays on, try one of the following methods to reset it:
Drive at or above 50 mph for 10 minutes. This can cause the tire pressure sensor to reset the next time you turn on the car.
With the vehicle off, turn the key to the “on” position, but don’t start the car. Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait 20 minutes for the sensor to refresh. The TPMS reset button is usually located beneath the steering wheel. If you are unable to find it, refer to your vehicle’s owner’s manual.
Inflate all tires to 3 PSI over their recommended amount, then deflate them completely. Be sure to include the spare tire, as it may have a sensor as well. Once they’re all deflated, re-inflate to the recommended tire pressure.
With the vehicle off, disconnect the positive battery cable. Turn the car on and honk the horn for about three seconds. This will discharge any power still stored in the vehicle. Then reconnect the battery.
