Modern vehicles are equipped with sophisticated systems designed to keep drivers informed and safe on the road. One of the most essential of these systems is the Tire Pressure Monitoring System (TPMS), which alerts you when one or more of your tires are underinflated. If you drive a 2006 Toyota 4Runner, you’ve likely encountered the iconic tire pressure warning light on your dashboard, leaving you wondering how to turn it off. After all, this warning doesn’t just go away once the issue is fixed — you usually need to manually reset the system.
In this guide, we’ll walk you through the entire process of resetting the tire pressure light on a 2006 Toyota 4Runner. Whether you’re a seasoned mechanic or a first-time DIY-er, this article provides clear, concise, and actionable instructions. Plus, we’ll address common questions, troubleshooting tips, and best practices to help you maintain optimal tire pressure for safety, fuel efficiency, and longevity.
Why the Tire Pressure Light Turns On
Before diving into the reset process, it’s essential to understand why the tire pressure light turns on in the first place. The 2006 Toyota 4Runner, like many vehicles of that era, is equipped with a direct TPMS. This means each wheel has a tire pressure sensor that sends real-time data to the vehicle’s computer system. When one or more tires fall below the recommended pressure (usually 32–35 PSI), the system triggers the warning light.
There are several reasons the tire pressure light might illuminate:
- Low tire pressure due to temperature changes, slow leaks, or normal wear
- Improper inflation after tire rotation or service
- Dead battery in the TPMS sensor
- Dirty or malfunctioning TPMS sensors
- After replacing one or more tires or wheels
Therefore, the first step is to check your tire pressure and ensure all four tires — and sometimes the spare — are properly inflated. But even after correcting the pressure, the TPMS light may stay on. That’s where a reset is necessary.
How to Reset the TPMS Light on a 2006 Toyota 4Runner
Unlike later models or newer vehicles with push-button TPMS resets, the 2006 Toyota 4Runner uses a slightly unique method. Since it predates widespread standardized TPMS systems, this model does not have a dedicated TPMS reset button. Instead, it requires a specific sequence of steps involving the ignition and possibly the brake pedal.
Step-by-Step Instructions
- Ensure All Tires Are Properly Inflated: Use a tire pressure gauge to check each tire. The recommended pressure is listed on the driver’s side door jamb or in the owner’s manual.
- Locate the TPMS Reset Port: The 2006 Toyota 4Runner has a reset port located under the steering wheel, near the emergency brake. It may be labeled or covered by a small rubber cap. This port is used to connect a TPMS reset tool or scanner.
- Use a TPMS Reset Tool or Scanner: Some auto parts stores sell or lend TPMS reset tools (e.g., the EZ-sensor or T8000 scanner). This device communicates with the vehicle’s ECU and resets the system.
- Connect the Scanner and Follow Instructions: With the key in the “On” position (but engine off), connect the scanner. Follow the on-screen prompts to relearn the sensor IDs, initialize the system, and perform a reset.
- Power Off and Restart: Turn the ignition off, wait a few seconds, then power it back on. The tire pressure light should illuminate briefly and then turn off — a sign that the system has reset.
- Drive the Vehicle: In some cases, the system may take a few minutes or a short drive to fully reset and begin monitoring the sensors again.
Alternative Method for Vehicles Without TPMS Tools
If you don’t have access to a TPMS scanner, some owners have reported success using the following alternative approach:
- Ensure all tires are correctly inflated to the recommended pressure.
- Turn the ignition to the “On” position without starting the engine.
- Press the brake pedal fully three times within five seconds.
- Turn the ignition off and then back on.
- Wait a few minutes or drive for a short distance to see if the TPMS light goes off.
Note: This alternative method may not work on all 2006 Toyota 4Runners, as it depends on the specific TPMS configuration and ECU settings. For best results, always use a TPMS scanner.
Why Using a TPMS Scanner Is Recommended
While the alternative reset method might work occasionally, the safest and most reliable way to reset the TPMS light is by using a TPMS scan tool. This is especially true if you’ve replaced sensors, performed tire rotations, or changed wheels.
Benefits of Using a TPMS Scanner
- Relearns Sensor IDs: Ensures each sensor communicates with the correct wheel position.
- Clears Fault Codes: Identifies and removes any error codes in the system.
- Updates Sensor Battery Status: Informs you if a sensor battery is low or dead.
- Improves Accuracy: Allows the system to recalibrate and monitor tire pressure more effectively.
The most accurate reset is done using professional TPMS tools like the Autel MaxiTPMS TS401, Accutire TS-601, or the Coats 6029TPMS. These tools can be purchased online or borrowed from some auto parts stores such as O’Reilly Auto Parts or Advance Auto Parts.
Common Issues and Troubleshooting Tips
The Light Comes Back On After Resetting
If the tire pressure light comes back on after resetting, it could indicate:
- One or more tires still have low pressure
- TPMS sensor is damaged or malfunctioning
- Sensor ID mismatch
- Electrical issues with the TPMS module
What to Do:
- Recheck tire pressure with a quality gauge.
- Inspect tires for visible signs of damage or leaks.

Preventive Maintenance Tips for Optimal Tire Pressure
Maintaining proper tire pressure is not only important for resetting the TPMS — it also affects your vehicle’s performance, fuel economy, handling, and safety. Here are a few preventive measures you can take:
Regular Tire Pressure Checks
- Check pressure when tires are cold (not driven on for at least three hours).
- Use a digital tire pressure gauge for accuracy.
- Check the pressure of all five tires, including the spare.
Monitor Temperature Fluctuations
Tires lose pressure when exposed to cold weather — approximately 1 PSI for every 10°F (5.5°C) drop in temperature. During seasonal changes, especially in the fall and winter, be extra vigilant about tire pressure.
Visual Tire Inspections
Examine tires for punctures, uneven wear, or bulges. These can affect pressure and may require early tire replacement.
Proper Tire Rotation Schedule
Rotate your tires every 5,000 to 7,500 miles. This helps maintain even wear and pressure distribution across all four tires, which supports stable TPMS notifications.
When Should You Go to a Professional?
If you’ve tried all the methods to reset the TPMS and the light keeps coming on, it might be time to visit a Toyota dealership or certified technician. Their diagnostic tools can provide a deeper assessment of sensor health, electrical issues, or ECU malfunctions.
You should also seek professional help if:
- You’re installing new wheels or tires and need sensor reprogramming.
- You’ve had recent brake or suspension work that might have interfered with the TPMS system.
- The TPMS light stays on consistently and seems unresponsive to manual resets.

So take the time to reset and maintain it properly, and your 2006 Toyota 4Runner will continue to serve you reliably for years to come.
Why does the tire pressure light stay on after inflating the tires?
The tire pressure light, or TPMS (Tire Pressure Monitoring System), in your 2006 Toyota 4Runner may stay on even after inflating your tires due to a variety of reasons. Typically, this happens because the system has not been reset after the tires were adjusted. Additionally, the sensor might need more time to recalibrate, especially if the vehicle wasn’t driven long enough after inflation. Extreme temperature changes can also impact tire pressure and may cause the light to remain illuminated temporarily.
To ensure the TPMS recognizes the new pressure settings, you must reset the system manually. This involves turning the ignition to the “ON” position, locating the TPMS reset button (usually beneath the steering wheel), and holding it until the TPMS light blinks. Once done, drive the vehicle for at least 15–20 minutes to allow the sensors to re-sync. If the light still doesn’t go off, check the tire pressure again and verify that all sensors are functioning properly.
Where is the TPMS reset button located on a 2006 Toyota 4Runner?
The TPMS reset button on a 2006 Toyota 4Runner is typically located beneath the steering wheel, on the driver’s side, and may be tucked inside a small hole in the dashboard or mounted on a small panel. It’s not always clearly marked, but you should look for a button labeled with “TPMS” or one with a tire icon. In some models, the button might be near the OBD-II port or within easy reach from the driver’s seat. Consulting the owner’s manual can help pinpoint the exact location if it’s not immediately visible.
Once you locate the button, use a small tool like a paperclip or a slender screwdriver to press and hold it while the ignition is in the “ON” position. The TPMS light on the dashboard should blink to indicate that the system is resetting. After the reset, it’s recommended to take a short drive to let the sensors recalibrate properly. Should the button fail to work, it could be faulty or disconnected, and a mechanic should inspect the system.
Can I reset the tire pressure light without a reset button?
Some 2006 Toyota 4Runner models may not feature a physical TPMS reset button, which means the system resets automatically after driving a certain distance once tire pressures have been corrected. If your vehicle doesn’t have a manual reset button, the solution is often to inflate or deflate the tires as needed and then drive the vehicle for at least 10–15 minutes at highway speed. This allows the sensors to register the new pressure levels and turn off the warning light on their own.
If the light remains on after this drive, it may indicate an issue with one of the tire pressure sensors or the system itself. In such cases, using a TPMS tool to manually relearn the sensors may be necessary. If you are unfamiliar with this process or lack the proper equipment, it’s best to visit a dealership or certified mechanic who can use specialized diagnostic tools to reset or recalibrate the system.
What should I do if the tire pressure light keeps coming back on?
If the tire pressure light keeps coming back on after resetting, it’s essential to check for underlying issues that may be affecting the tire pressure monitoring system. Begin by checking each tire manually with a pressure gauge to ensure they are inflated to the recommended PSI, which can be found on the driver’s side door jamb or in the owner’s manual. Sometimes even a small leak can trigger the system, so inspect tires for punctures, damaged valve stems, or improper bead seating.
Additionally, a recurring TPMS light may indicate a malfunction in one of the wheel sensors. Over time, the valve stems can corrode or the sensors can lose battery power, especially in older vehicles like the 2006 Toyota 4Runner. If individual tire pressure checks prove successful but the light persists, you may need to replace a faulty sensor or visit a mechanic to properly diagnose and repair the TPMS.
How often should I check the tire pressure on my 2006 Toyota 4Runner?
It’s recommended to check the tire pressure on your 2006 Toyota 4Runner at least once a month and before long trips. Tire pressure can fluctuate due to changes in temperature, and under-inflated or over-inflated tires can affect fuel efficiency, handling, and overall safety. Regular checking ensures that the TPMS doesn’t falsely trigger due to minor pressure variations and that your vehicle operates at peak performance.
It’s also wise to check your tire pressure when the seasons change, especially during colder months when pressure tends to drop. In addition to visual inspections and pressure checks, rotating your tires every 5,000 to 7,000 miles can help maintain even wear and prolong tread life. If you’ve recently reset your TPMS light, checking the pressure manually can help avoid confusion as the system calibrates itself during normal driving.
Do I need to reset the TPMS after replacing a tire?
Yes, if you’ve replaced a tire on your 2006 Toyota 4Runner, especially with one that includes a new TPMS sensor, you’ll likely need to reset the system to allow it to recognize the new components. Replacing a tire or wheel can disrupt the communication between the TPMS sensors and the vehicle’s main computer, and the system may not function correctly until it is recalibrated. In some cases, the sensor may need to be relearned using a TPMS tool.
The TPMS reset process is usually the same as routine resets—pressing the reset button while the ignition is in the “ON” position or allowing the system to reset itself as you drive. However, more advanced recalibration might be needed if the new tire includes a different sensor that isn’t automatically recognized. If you’re unsure about the process or have installed aftermarket wheels or sensors, it’s safest to bring your vehicle to a qualified technician or dealership for a reset and sensor relearning.
Is it safe to drive with the tire pressure light on?
Driving with the tire pressure light on is not recommended for extended periods, as it indicates that at least one tire is underinflated, which can affect vehicle handling, fuel efficiency, and tire longevity. Underinflated tires generate more heat and increase the risk of blowouts, especially at higher speeds or in hot weather. Moreover, the TPMS warning is a critical safety feature, and ignoring it could lead to more severe issues like uneven tire wear or loss of vehicle control in emergency situations.
However, short-distance driving, such as getting to the nearest gas station or tire shop, should be safe as long as you’re cautious and conscious of reduced handling. Once the light turns on, your immediate action should include checking tire pressure, making necessary adjustments, and resetting the TPMS to ensure the warning system reflects accurate readings. If the light doesn’t turn off after correcting pressure and resetting, further diagnostics may be required.
