The Tire Pressure Monitoring System (TPMS) in your Toyota Camry is a crucial safety feature. It constantly monitors the air pressure in your tires and alerts you when the pressure drops below a certain threshold. This helps prevent accidents caused by underinflated tires, improves fuel efficiency, and extends tire life. However, sometimes the TPMS light can come on even when your tire pressures are correct. This can be frustrating, but thankfully, resetting the TPMS light on your Camry is usually a straightforward process.
Understanding Your Camry’s TPMS
Before diving into the reset procedures, it’s essential to understand how your Camry’s TPMS works and what can trigger the warning light. The system uses sensors located inside each wheel to measure tire pressure. These sensors transmit the data wirelessly to the car’s computer. If the pressure in one or more tires falls below the recommended level (typically around 25% below the recommended PSI), the TPMS light will illuminate on your dashboard.
Several factors can cause the TPMS light to come on:
- Low Tire Pressure: This is the most common reason. Changes in temperature can cause tire pressure to fluctuate.
- Faulty TPMS Sensor: The sensors have a limited lifespan, usually around 5-7 years. They can fail due to battery depletion or physical damage.
- TPMS Sensor Battery: Each sensor is powered by a battery that eventually dies.
- Recent Tire Change or Rotation: If your tires have recently been changed or rotated, the system may need to be recalibrated.
- Electrical Issues: In rare cases, electrical problems within the TPMS system can trigger the light.
- Aftermarket Tire Inflators: Some aftermarket tire inflators can damage the sensors if not used carefully.
- Temperature changes: Significant drops in temperature can cause tire pressure to decrease, triggering the TPMS light.
Preparing to Reset the TPMS Light
Before attempting to reset the TPMS light, it’s vital to ensure your tires are properly inflated. Use a reliable tire pressure gauge to check the pressure in all four tires, including the spare if applicable. Inflate each tire to the pressure recommended on the sticker located on the driver’s side doorjamb. This sticker provides the optimal tire pressure for your specific Camry model.
Checking the spare tire is important even if your Camry doesn’t have a sensor in the spare. Ensuring proper inflation in the spare will allow you to deal with a flat if you get one while driving.
It is also important to check for any physical damage to the tires or wheels. Any significant damage could affect the TPMS reading and should be addressed before resetting the light.

What is a TPMS light and why is it important?
The TPMS (Tire Pressure Monitoring System) light on your Toyota Camry’s dashboard indicates that one or more of your tires have incorrect tire pressure. This system uses sensors inside your tires to monitor the pressure and alerts you when it falls below or rises above a certain threshold. The light can appear as a tire symbol with an exclamation point inside, or simply as the word “TPMS.”
Maintaining proper tire pressure is crucial for several reasons. It improves fuel efficiency, extends the life of your tires by reducing wear and tear, and enhances handling and braking performance, contributing to overall driving safety. Ignoring the TPMS light could lead to tire damage, reduced fuel economy, and a higher risk of accidents. Therefore, it’s essential to address the issue promptly when the light illuminates.
What are the common reasons for the TPMS light to come on in a Toyota Camry?
The most common reason for the TPMS light to illuminate is simply low tire pressure. Temperature fluctuations can cause tire pressure to decrease, especially during colder weather. A slow leak from a puncture, valve stem issue, or bead leak can also lead to gradual pressure loss and trigger the sensor. Make sure to always check your tire pressure, as this is the most common culprit.
Other potential causes include a faulty TPMS sensor, which can happen as the sensors age or experience damage. Sometimes, changing tires without properly resetting or programming the TPMS system can also trigger the light. Additionally, interference from electronic devices or other vehicles with similar TPMS systems can occasionally cause false readings, although this is less frequent.
How do I check my tire pressure on a Toyota Camry?
First, locate the recommended tire pressure for your Toyota Camry. This information is typically found on a sticker inside the driver’s side doorjamb or in your owner’s manual. Use a reliable tire pressure gauge to check the pressure in each tire, including the spare if applicable. Remove the valve cap, firmly press the gauge onto the valve stem, and read the measurement displayed on the gauge.
It’s best to check tire pressure when the tires are cold, meaning they haven’t been driven on for at least three hours. If you have recently driven, wait a few hours for the tires to cool down before checking. If any tires are below the recommended pressure, use an air compressor to inflate them to the correct level. Once you’ve adjusted the pressure, recheck with the gauge to ensure accuracy.
What is the TPMS reset button and where is it located on a Toyota Camry?
The TPMS reset button on a Toyota Camry is designed to recalibrate the system after adjusting tire pressures or replacing tires. Pressing this button tells the system to learn the current tire pressures as the new baseline. This ensures the system accurately monitors pressure fluctuations and provides reliable warnings.
The location of the TPMS reset button can vary slightly depending on the year and trim level of your Camry. However, it’s typically found located under the steering wheel, near the glove compartment, or sometimes inside the glove compartment itself. Consult your owner’s manual for the exact location specific to your vehicle model and year if you are unsure.
How do I reset the TPMS light using the reset button method on my Camry?
To reset the TPMS light using the reset button, first ensure that all your tires are inflated to the recommended pressure listed on the sticker inside the driver’s side doorjamb.

Press and hold the TPMS reset button until the TPMS indicator light on the dashboard blinks three times. This usually takes about 3-5 seconds. Release the button. Start the engine and drive the vehicle for about 10 minutes at a speed of at least 25 mph. This allows the TPMS sensors to communicate with the vehicle’s computer and learn the new tire pressures. The TPMS light should turn off after this process.
What if the TPMS light doesn’t turn off after resetting it?
If the TPMS light remains on after resetting the system, there are a few potential issues. Double-check that all tires are inflated to the correct pressure and that there are no leaks. A slow leak can cause the pressure to drop again shortly after resetting, triggering the light to reappear. Also, ensure you followed the reset procedure correctly, including driving the vehicle for the specified duration and speed.
If the problem persists, one or more of the TPMS sensors may be faulty or have a dead battery. These sensors typically last for 5-7 years, and replacement may be necessary. Another possibility is a problem with the TPMS system itself, requiring a diagnostic scan by a qualified mechanic to identify the root cause and perform necessary repairs. It is important to have the system inspected for peace of mind.
Are there any other methods to reset the TPMS light on a Toyota Camry?
While the reset button method is the most common and reliable way to reset the TPMS light on a Toyota Camry, some models may allow for a reset through the vehicle’s infotainment system or multi-information display. Check your owner’s manual to see if your Camry model has this feature. The steps typically involve navigating through the vehicle’s settings menu to find the TPMS or tire pressure calibration option.
Another less reliable method sometimes suggested is the “air down and inflate” technique. This involves deflating all tires completely and then inflating them back to the recommended pressure. However, this method is not officially recommended by Toyota and may not always work. The reset button method or a professional diagnostic scan is generally preferred for a more accurate and reliable solution.
