Your Toyota tire pressure light blinks when the system is having problems. This usually means a sensor is not working or there is an error in the system. A reset or sensor check can fix the issue.
This article will break down the reasons behind a blinking tire pressure.
What is TPMS?
TPMS stands for Tire Pressure Monitoring System. It checks the air in your car tires. If the tire air gets low a warning light shows. TPMS helps ensure safe driving better fuel use and longer tire life.
Common Causes of a Blinking Tire Pressure Light:
Your tire pressure light blinks something is wrong with your Tire Pressure Monitoring System (TPMS).
Here are the most common reasons why it happens.
1. Low Tire Pressure:
- This is the most common cause.
- Your tires may have less air than needed.
- It can happen because of cold weather, minor leaks or time.
- Always check your tires and fill them with air if needed.
2. Dead or Bad TPMS Sensor:
- Your car has small sensors in each tire.
- These sensors send air pressure info to your dashboard.
- If a sensor is broken or dead the light will blink.
- You may need to replace the sensor.
3. Cold Weather Effect:
- In winter the air inside tires shrinks.
- This makes the tire pressure go lower and the light blinks.
- You may not leak it’s just cold weather.
- Add a little air to fix this.

4. Tire Leak or Damaged Valve:
- If a hole in the tire or the valve is broken air can leak out.
- This will make the pressure low and trigger the light.
- Check for slow leaks or damaged valves.
5. TPMS System Problem:
- Sometimes the system itself is the problem.
- If the light blinks for 1 minute and stays on the TPMS is not working right.
- You will need a mechanic or a tire shop to check and fix it.
How do you reset your Toyota tire pressure light?
- Check all your tires and ensure they have the correct air pressure. The proper PSI number is on the driver’s side door or in the car manual.
- Sit in your car and turn the key to “ON” (do not start the engine).
- Look under the steering wheel. Find the small button called the TPMS reset button.
- Press and hold this button for 3 to 5 seconds. The tire pressure light will blink.
- Now start your car and drive for 10-20 minutes. The tire light will turn off.
- If the light stays on, one sensor may be faulty. Visit a Toyota service center for help.

How much air should be in your tires?
Most cars need 30 to 35 psi of air in their tires. Check the sticker on the driver’s door or the car manual. Always check tire pressure when tires are cold. Proper air pressure helps the car drive smoothly, saves fuel, and keeps tires safe. Low or high air pressure can damage tires.
Can I drive with a blinking tire pressure light?
No, you do not drive if the tire light is blinking. This means the system is not working. It may not show if the tire air is low. Check the air by hand and go to a tire shop. Fix the issue first, then drive. It keeps you and your car safe.
Where is the Toyota TPMS reset button?
The Toyota TPMS reset button is usually under the steering wheel, near your knees. In some models, it’s inside or beside the glove box. After checking tire pressure, press and hold the button until the tire light blinks. Then drive for a few minutes to complete the reset.
How much does fixing a blinking TPMS light on a Toyota cost?
| Service | Estimated Cost (Per Wheel) |
| New TPMS Sensor (OEM) | $50 – $75 |
| New TPMS Sensor (Aftermarket) | $20 – $40 |
| Labor / Installation | $10 – $50 |
| Programming / Relearning | $10 – $30 |
| 💡 Total Estimate | $30 – $125 per wheel |
Fixing a blinking TPMS light on your Toyota may cost $30 to $125 per wheel, depending on your car model, sensor type, and where you get it fixed.
How Long Do Toyota TPMS Sensors Last?
Toyota TPMS sensors usually last 7 to 10 years or about 100,000 miles, depending on usage and weather. They have a small battery inside that cannot be replaced. Once the battery dies, you need to change the whole sensor. Driving regularly and keeping tires in good shape can help them last longer.
FAQ’s:
1. How Do I Know If My TPMS Sensor Battery Is Dying?
The TPMS light blinks and stays on and the sensor battery may die. It can also show a tire warning even when the air is okay.
2. How Does Tire Temperature Influence TPMS Readings?
When tires are cold TPMS may show low pressure. When tires heat the pressure increases and the TPMS reading changes.
3. Do All Toyota Models Come Equipped with a TPMS Reset Button?
Not all Toyota models have a TPMS reset button. Some use automatic systems that reset after driving and adjusting tire pressure.
4. Can Using Nitrogen Instead of Air Affect the TPMS Readings?
Using nitrogen instead of air does not change TPMS readings. The sensor checks pressure not the type of gas inside the tire.
5. How Tire Rotation Practices Affect TPMS Calibration?
Tire rotation can confuse TPMS if it tracks tire positions. Some Toyotas reset it automatically others need a manual reset.
6. How to Diagnose a Blinking TPMS Light in Your Toyota?
A blinking TPMS light indicates a sensor problem. Check tire pressure first then use a scanner to locate the issue.
Conclusion:
A blinking tire pressure light in your Toyota often means low air sensor issues or cold weather effects. Always check tire pressure first. If the light stays on try using the TPMS reset button. Replace bad sensors if needed. Fixing TPMS problems quickly keeps your tires safe, improves fuel use and helps your car drive better.
