Toyota Tire Pressure Light Blinks Then Stays on

When the tire pressure light on your Toyota blinks and then stays on, it signals a potential issue with the Tire Pressure Monitoring System (TPMS), such as a sensor or battery problem. This behavior is more than just an electronic quirk; it’s an urgent alert indicating a communication breakdown with one or more TPMS sensors.

Unlike a constant light, which indicates low tire pressure, a blinking light demands immediate attention to prevent any safety or performance issues. Understanding and addressing this issue promptly is crucial for ensuring a safe and smooth driving experience.

Understanding the TPMS

The Tire Pressure Monitoring System (TPMS) alerts you when tire pressure is too low, potentially preventing damage and ensuring your vehicle’s optimal performance. For Toyota owners, understanding the TPMS is crucial.

When the tire pressure light stays on, it’s a clear signal to check your tires’ pressure. However, if the TPMS light flashes before staying lit, it indicates a more serious issue, likely related to the sensor battery or the sensor itself. This blinking warning requires a trip to a Toyota service center for a diagnostic check.

Resetting the TPMS can involve several methods, including driving at 50 mph, utilizing the TPMS reset button, or disconnecting the vehicle’s positive battery cable and honking the horn to reset the system. Always refer to your Toyota manual for the recommended air pressure and detailed TPMS reset procedures.

Causes of Blinking Lights

Several factors can cause your Toyota’s tire pressure light to blink, ranging from electrical issues to a malfunction in the TPMS system. When the Toyota tire pressure light blinks before staying on, it’s a clear signal that something isn’t right.

  • Electrical Issues: A problem with the car battery or there’s a faulty connection. If the sensor blinks three times, it might indicate a battery issue. Always check your owner’s manual for specific guidance.
  • Low PSI: Sudden drops in tire pressure can trigger the blinking light. This is a straightforward fix by adjusting the pressure to the recommended PSI.
  • TPMS Malfunctions: If the TPMS reset button doesn’t resolve the blinking light, the issue could be a malfunction within the TPMS itself or a faulty pressure sensor.

Safety Implications

Understanding the causes of a blinking TPMS light is crucial, but it’s equally important to grasp the safety implications such issues can have on your driving experience.

When your Toyota’s tire pressure light blinks then stays on, it signals potential low PSI that could diminish vehicle stability and control. If neglected, this can increase the risk of accidents, particularly during emergency maneuvers or in adverse conditions.

Regularly check your Toyota Camry to ensure the TPMS is accurately monitoring air pressure. A malfunctioning tire pressure sensor not only leads to uneven wear but also compromises critical safety systems like stability control and anti-lock brakes.

Maintaining proper tire pressure is essential; ignoring a consistent TPMS warning can severely impact traction, and braking distances, and increase hydroplaning risk, endangering all occupants.

Resetting the Light

Once you’ve acknowledged the safety concerns, it’s crucial to know how to properly reset the tire pressure light in your Toyota to maintain optimal tire performance and safety. Following these detailed steps will ensure the TPMS (Tire Pressure Monitoring System) is accurately monitoring your tires:

  • Check the pressure in all tires, including the spare, to ensure they’re properly inflated according to Toyota’s specifications.
  • Turn your car on without starting the engine, then find and press the TPMS reset button until the pressure light blinks three times.
  • Drive your Toyota for at least 20 minutes at 15 mph or more. This allows the sensors to reset.

Maintaining Proper Tire Pressure

To maintain your Toyota’s tire lifespan and performance, regularly check the tire pressure, ensuring it aligns with the manufacturer’s recommendations. Maintaining proper tire pressure is crucial for avoiding issues like uneven wear and reduced fuel efficiency.

The Tire Pressure Monitoring System (TPMS) alerts you to low PSI, but knowing the recommended levels is essential. For instance, cars like the Toyota RAV4 recommend 32-33 PSI, though tire sizes require different pressures. Always refer to your car’s manual for precise figures.

If your TPMS light signals a problem, resetting it involves driving at 50 mph for ten minutes or utilizing the reset button. For persistent issues, consult a Toyota service center for expert sensor checks and air adjustments.


In conclusion, if your Toyota’s tire pressure light blinks before staying on, it’s signaling a potential issue with a TPMS sensor or its battery. Don’t ignore this warning. It’s crucial for your safety and the integrity of the system.

Regularly check your tire pressure and bring your vehicle to a service center for a diagnostic. Resetting the light might be necessary, but understanding the root cause is key to preventing future occurrences and ensuring your TPMS functions correctly.
