How to Replace a Tire Pressure Sensor
Replacing a tire pressure sensor (TPMS sensor) is a task that can be handled by most do-it-yourself enthusiasts with the right tools and safety precautions. Here's a step-by-step guide to help you through the process. Please note, vehicle specifics can vary, so it's always a good idea to consult your vehicle's manual for any specific requirements or instructions.
Supplies
- New TPMS sensor(s) specific to your vehicle model
- Tire changer machine (for demounting and mounting the tire)
- TPMS programming tool (if required by your vehicle)
- Torque wrench
- Valve stem removal tool
- Socket set
- Tire valve core removal tool
- Tire bead seal (optional)
- Safety glasses and gloves
Preparation
- Purchase the Correct TPMS Sensor: Ensure you buy the right TPMS sensor for your vehicle’s make, model, and year. If you are not sure, purchase a universal TPMS sensor such as an Autel tire pressure sensor.
- Safety First: Put on safety glasses and gloves to protect yourself during the process.
Remove the Tire From the Wheel
- Loosen the Lug Nuts: With the vehicle on the ground, loosen the lug nuts on the wheel where the TPMS sensor needs to be replaced. Don't remove them completely yet.
- Lift the Vehicle: Use a jack to lift the vehicle. Place it under the vehicle's designated lift points to avoid damage. Secure the vehicle with jack stands.
- Remove the Wheel: Remove the lug nuts completely and take the wheel off the vehicle.
Demount the Tire
- Deflate the Tire: Remove the valve core with a valve core removal tool to release the air from the tire.
- Demount the Tire: Use a tire changer machine to carefully demount the tire from the rim or wheel. This exposes the TPMS sensor, which is located at the base of the valve stem inside the wheel.
Replace the Tire Pressure Sensor
- Remove the Old TPMS Sensor: Unscrew (usually a T10 torx) or unclip the TPMS sensor from the wheel. Use a valve stem removal tool to pull the valve stem out of the valve stem hole. Take note of its orientation and how it was installed.
- Install the New TPMS Sensor: Pull the new sensor into the valve stem hole using a valve removal tool into the same position as the old one. If it comes with a new valve stem, ensure it's correctly installed. Tighten any screws or nuts to the manufacturer's specified torque.
Remount the Tire to the Wheel
- Check the Rim: Ensure the rim is clean and free of debris. Clean with a wire wheel if necessary. Apply tire bead seal if necessary.
- Mount the Tire: Use the tire changer to mount the tire back onto the rim.
- Inflate the Tire: Inflate the tire to the recommended pressure for your vehicle.
Reinstall the Wheel on the Vehicle
- Mount the Wheel: Place the wheel back on the vehicle's hub.
- Tighten the Lug Nuts: Hand-tighten the lug nuts and then tighten with impact wrench in a star pattern to ensure even distribution of pressure.
- Lower the Vehicle: Remove the jack stands and lower the vehicle back to the ground.
- Final Tightening: Use a torque wrench to tighten the lug nuts to the vehicle manufacturer’s recommended torque setting.
Reset the Tire Pressure Monitoring System
Reset/Relearn TPMS: Some vehicles require a TPMS reset or relearn procedure after installing new sensors. Consult your vehicle's manual for specific instructions. You will need a TPMS reset tool for this step if you have used a universal tire pressure sensor.
Conclusion
By following these steps carefully, you can successfully replace a tire pressure sensor and ensure your vehicle’s tire pressure monitoring system is functioning correctly. To learn more about tires, tire pressure sensors, and TPMS visit TPMS Reset.
