TPMS Relearn Tool Best 2025 Buying Guide & How to Use for DIY

The Tire Pressure Monitoring System (TPMS) is a crucial feature in modern vehicles, ensuring that drivers maintain proper tire pressure for safety and efficiency. However, after replacing or rotating tires, or installing new TPMS sensors, a relearn procedure is required to synchronize the new sensors with the vehicle’s ECU. This is where a TPMS Relearn Tool comes in handy.

For DIY car owners and professionals alike, investing in a high-quality TPMS tool can save time and money. In this guide, we will review two of the best TPMS relearn tools in 2025: the XTOOL TP150 and IP819TP. These tools offer advanced functionalities, making TPMS servicing seamless and efficient.

Why Do You Need a TPMS Relearn Tool?

A TPMS relearn tool is necessary for several situations, including:

• Tire Replacement or Rotation: Ensuring that the system recognizes the correct position of each sensor.
• New TPMS Sensor Installation: Pairing newly installed sensors with the vehicle's TPMS system.
• Fixing TPMS Warning Light Issues: Resetting the warning light after adjusting tire pressure or replacing a faulty sensor.

Using a TPMS tool like the XTOOL TP150 or IP819TP can make these tasks quick and hassle-free.

How to Use a TPMS Relearn Tool (DIY Guide)

Using a TPMS relearn tool is straightforward if you follow these steps:

Step 1: Check Your Vehicle’s TPMS Mode

Before starting, consult your vehicle’s owner manual to determine the TPMS relearn procedure. Some cars require manual relearn, while others automatically sync after driving a short distance.

Step 2: Turn On the Ignition

Start the vehicle and ensure it is in the correct mode for TPMS relearning. Some vehicles may require pressing specific buttons or using an OBD2 scanner.

Step 3: Activate TPMS Sensors

Using the XTOOL TP150 or IP819TP, hold the tool near the tire’s valve stem and press the activation button. Repeat for all four tires in the correct order (usually front-left, front-right, rear-right, rear-left).

Step 4: Complete the Relearn Process

Once all sensors are activated, the vehicle may confirm the process by flashing the TPMS light or sounding a beep. If using an OBD2-compatible tool like the IP819TP, follow on-screen prompts to complete the relearn.

Step 5: Verify System Functionality

After relearning, check the TPMS display on your dashboard to ensure proper tire pressure readings. If issues persist, repeat the process or check for sensor faults using the diagnostic feature.

Conclusion: Which TPMS Tool Should You Choose?

Both XTOOL TP150 and IP819TP are excellent choices, but which one suits your needs best?
