How to Reset Tire Pressure Light

If you’ve just recently inflated your tires, it can be frustrating to see a flashing tire pressure light from your TPMS (Tire Pressure Monitoring System). This system uses a variety of sensors that monitor your tire pressure in each wheel for over- or under-inflation. Sometimes, however, it can malfunction, and while it’s important to check the TPMS system on your Acura for warnings and heed them, it’s also useful to read our “TMPS: How to Reset” guide, in case your warning lights get stuck, so you can turn that annoying light off!

In this guide from the Southview Acura service centre, we’ll cover the reasons that your car’s dash still has the TPMS light on, and how to reset your tire pressure light after inflating your tires. The process should take just a few minutes, and it’s easy to do at home in Grand Prairie — but don’t hesitate to reach out with any questions!

How to Turn Off a Flashing Tire Pressure Light

The flashing tire pressure light should cease after you refill your tires, but occasional glitches in the tire pressure monitoring system can keep the TPMS light on even after a refill. You can either schedule service at an Acura service centre to have a professional check the TPMS system in your Acura, or you can read this “TPMS: How to Reset” guide and learn how to reset the tire pressure light yourself if you’re comfortable with basic DIY auto maintenance! Follow these steps to reset a rogue flashing tire pressure light:

• Drive at or above 80 km/h for 10 minutes. Just this step alone may trigger the sensor to reset the next time you start the car.
• If step one doesn’t work, park your car and shut off the ignition. Turn the key to “On” (one position to the right), but don’t start the car. Now hold down the “TPMS Reset” button until the flashing tire pressure light blinks three times. Start the engine and wait 20 minutes. Check your owner’s manual if you have trouble finding the reset button. You’ll usually find it beneath the steering wheel.
• Still no luck? Try inflating all four tires to 3 PSI over their recommended amount and then deflate them fully. Finally, inflate them again to the recommended pressure.
• If the little trooper is still flashing, try this last strategy: cut the engine, use a wrench to disconnect the positive battery cable, start the car again, and then lay on the horn for about three seconds. Doing so should discharge any remaining power stored in the system. After that, you’ll want to reconnect the battery, start the car, and see if the TPMS light is on or off.
