1. Introducció
The Autel MaxiTPMS MX-Sensor is a universal programmable Tire Pressure Monitoring System (TPMS) sensor designed to replace original equipment (OE) sensors. It combines both 315MHz and 433MHz frequencies into a single sensor, offering broad vehicle coverage. This sensor is compatible with Autel MaxiTPMS diagnostic tools for activation, programming, and relearning procedures.

2. Configuració i instal·lació
Proper installation of the MX-Sensor is crucial for accurate tire pressure monitoring. The sensor features interchangeable rubber and metal valve stems to accommodate various wheel types. Installation requires specialized tire service equipment and should ideally be performed by a trained technician.
2.1 Components of the MX-Sensor

2.2 Procediment d'instal·lació
The following steps outline the general installation process. Always refer to vehicle-specific service manuals for precise instructions.
- Loosen the Tire: Use appropriate equipment to loosen the tire from the wheel rim.
- Dismount the Tire: Carefully dismount the tire from the wheel using a tire changer.
- Dismount the Old Sensor: Remove the existing TPMS sensor from the wheel.
- Mount the New MX-Sensor and Valve: Insert the new MX-Sensor and ensure the sensor body and valve stem are firmly connected. The interchangeable valve stems allow for easy replacement without special tools.
- Mount the Tire: Mount the tire back onto the wheel, ensuring proper seating.
- Inflate and Balance: Inflate the tire to the recommended pressure and balance the wheel.

2.3 Sensor Programming and Relearning
After physical installation, the MX-Sensor must be programmed and relearned to the vehicle's TPMS system using a compatible Autel MaxiTPMS tool (e.g., TS408, TS508, TS608, MK808TS, ITS600, MS906Pro-TS). This process typically involves:
- Activació: Waking up the new sensor.
- Programació: Transferring the vehicle's original sensor ID or generating a new one to the MX-Sensor. The MX-Sensor supports 100% ID cloning, allowing direct replacement without relearning in some cases.
- Relearning: Registering the new sensor IDs with the vehicle's Engine Control Unit (ECU).

3. Principis de funcionament
The Autel MX-Sensor continuously monitors tire pressure and temperature, transmitting this data wirelessly to the vehicle's TPMS receiver. This system alerts the driver to under-inflated tires or significant pressure drops, contributing to driving safety and tire longevity.
- Freqüència dual: Operates on both 315MHz and 433MHz frequencies, ensuring compatibility with a wide range of vehicles globally.
- Monitorització en temps real: Provides continuous updates on tire pressure and temperature.
- Programació sense fil: Can be programmed wirelessly using Autel TPMS tools, often allowing multiple sensors to be programmed simultaneously.
- ID Cloning: Supports cloning of existing sensor IDs, simplifying replacement procedures.

4. Manteniment
TPMS sensors are generally maintenance-free once installed and programmed. However, regular tire maintenance practices contribute to the longevity and proper function of the sensors:
- Regular Tire Pressure Checks: Even with TPMS, manually checking tire pressure periodically is recommended.
- Valve Stem Care: Ensure valve caps are securely fastened to prevent dirt and moisture ingress. Avoid overtightening.
- Servei professional: When tires are replaced or repaired, ensure that the TPMS sensors are handled by qualified personnel to prevent damage.
- Durada de la bateria: MX-Sensors have a long-lasting battery. When the battery depletes, the sensor will need to be replaced, as the battery is not user-replaceable.
5. Solució De Problemes
If you encounter issues with your TPMS system after installing MX-Sensors, consider the following common troubleshooting steps:
- TPMS Warning Light On: This indicates a tire pressure issue or a sensor malfunction. Check all tire pressures manually. If pressures are correct, the sensor may need reprogramming or replacement.
- Sensor no detectat: Ensure the sensor was correctly installed and programmed using an Autel TPMS tool. Verify the tool's software is up to date.
- Incorrect Pressure Readings: Recalibrate the sensor using an Autel TPMS tool. Ensure the tire pressure gauge used for manual checks is accurate.
- Intermittent Warnings: This could be due to a weak sensor battery or radio interference. If the battery is low, the sensor will need replacement.
For persistent issues, consult an automotive professional or contact Autel customer support.
