1. Product Introduction
The THINKCAR TP T90 Pro is a professional Tire Pressure Monitoring System (TPMS) service tool designed for comprehensive tire health management. It offers a wide range of functionalities including activation, reading, relearning, and programming of TPMS sensors. This plug-and-play tool is compatible with a vast array of American, European, and Asian manufactured vehicles.
The device activates pressure information by receiving signals via low or high radio frequency and can reset the TPMS module through the OBD port. It is an ideal choice for performing TPMS system diagnostics and general OBDII diagnostics.

3. Setup and Connection
3.1 Connecting the OBDII (EOBD) Diagnostic Cable
- Locate your vehicle's Data Link Connector (DLC) port. This is typically found under the dashboard on the driver's side.
- Connect the OBDII diagnostic cable from the THINKCAR TP T90 Pro to the vehicle's DLC port. This connection is necessary for OBD diagnosis functions and TPMS learning.
Note:
- The DLC port is used for activation or programming functions. Attempting to charge the tool via the OBD diagnostic port will consume the vehicle's battery power. It is not recommended to charge the tool this way, except during diagnosis operations.
- If the tool is properly connected to the vehicle's DLC, it will be charged automatically during operation.
4. Operating Instructions
4.1 Check Sensor
This function allows you to activate TPMS sensors and view sensor data such as ID, tire pressure, frequency, temperature, and battery condition.
- For initial use, navigate to the TPMS function menu by selecting the vehicle manufacturer, model, and year.
- Select 'Activate Sensor' and press the activation button on the tool.
- For universal sensors, place the tool alongside the valve stem, pointing towards the sensor location, and press the button.
Notes on Sensor Activation:
- For early magnet-activated sensors, place a magnet over the stem before positioning the tool alongside the valve stem.
- If the TPMS sensor requires tire deflation (approx. 10 PSI), deflate the tire, then place the tool alongside the stem while pressing the button.
- Once successfully activated and decoded, the tool will beep, and the screen will display sensor data with a tick.
- If a sensor fails to trigger, an icon will appear next to the wheel position.
- Abnormal sensor data will be displayed in red.
Interpreting Sensor Data:
- ID: Indicates the sensor ID.
- P: Indicates the tire pressure.
- T: Indicates the tire temperature.
- Vol: Indicates the battery power level.
4.2 Program Sensor
This function allows you to program sensor data to THINKCAR sensors, useful for replacing faulty sensors or those with low battery life. The THINKCAR TP T90 Pro supports programming up to 8 sensors simultaneously.
Programming Options:
- CREATE SENSOR: Programs a THINKCAR sensor with a randomly generated ID. Select the wheel, place a THINKCAR sensor close to the tool's TPMS antenna, and select 'CREATE SENSOR'.
- MANUAL INPUT: Allows manual entry of a sensor ID. You can enter either a random ID or the original sensor ID if available.
- COPY ID BY ACTIVATE: Writes the retrieved original sensor data to a new THINKCAR sensor after the original sensor has been triggered.
- CREATE MULTI-SENSOR (1-8): Programs multiple sensors (up to 8) at the same time.
Notes on Programming:
- If a random ID is used for programming, a TPMS Relearn function must be performed afterward.
- If the original ID is used, a Relearn function is not necessary.
- If the vehicle does not support the relearn function, use the Manual Input option to enter the original sensor ID, or trigger the original sensor at the activation interface to obtain its information before programming the THINKCAR sensor.
4.3 Relearn Sensor
The Relearn function is crucial for writing newly programmed sensor IDs into the vehicle's ECU, allowing the vehicle to recognize the new sensors. This operation is only required when the new sensor IDs differ from the original IDs stored in the vehicle's ECU.
Example Relearn Procedure (e.g., MERCEDES B Class 2014~2018 - Automatic/OBD):
- Inflate all tires to the nominal pressure value as indicated on the tire label (usually found on the door frame).
- Follow the on-screen prompts to 'Learn the new sensor ID'.
5. Maintenance and Firmware Update
5.1 Firmware Update
Regular firmware updates ensure your THINKCAR TP T90 Pro has the latest features and vehicle model coverage. The device offers free lifetime firmware updates.
General Guidance:
- Refer to the 'HELP - Software update guide' on your tool for detailed instructions.

8. User Tips
- Power Management: Always ensure the tool is adequately charged via the Type-C port for stable operation. While the OBD connection provides power, it is not recommended as the primary charging method to avoid draining the vehicle's battery unnecessarily.
- Vehicle Selection: For accurate TPMS functions, always correctly select your vehicle's manufacturer, model, and year in the tool's menu before proceeding with sensor checks or programming.
- Programming & Relearn: Pay close attention to whether you are programming a sensor with a random ID or an original ID. Random IDs will always require a subsequent TPMS Relearn procedure to be performed on the vehicle, whereas original IDs typically do not.
- Firmware Updates: When performing firmware updates, use a stable internet connection and the recommended browser (Google Chrome) to ensure the download package is complete and uncorrupted. If you encounter issues with multi-language support or device power-on after an update, contact THINKCAR customer service for direct assistance.
