How To Replace TPMS (Tire Pressure Monitoring System) Sensors Without A Tire Machine.

Introduction

This tutorial will guide you through the process of replacing Tire Pressure Monitoring System (TPMS) sensors at home without needing a tire machine. If your TPMS sensors are malfunctioning or the batteries are dead, you can perform this replacement using common tools. This method not only saves you money but also empowers you to maintain your vehicle.

Step 1: Remove the Wheel

1. Lift the Vehicle: Use a scissor jack or bottle jack to lift your vehicle.
2. Remove the Wheel: Once the vehicle is elevated, take off the wheel to access the tire.

Step 2: Release Air from the Tire

1. Remove the Valve Core: Use a valve core tool to extract the valve core from the tire stem. This will quickly deflate the tire.
2. Ensure Tire is Flat: Make sure the tire is completely deflated.

Step 3: Break the Bead on the Tire

1. Prepare the Jack: Place a block of wood on the ground and set the scissor jack on top of it. This will help protect the tire's sidewall.
2. Break the Bead:
   • Position the Jack: Place the jack against the sidewall of the tire.
   • Jack Down: Lower the jack, which will compress the sidewall and break the bead.
3. Alternative Method: If you don't have a scissor jack, use a long piece of wood to pry down on the tire sidewall.

Step 4: Remove the Old TPMS Sensor

1. Locate the Sensor: Identify the TPMS sensor attached to the valve stem.
2. Unscrew the Nut: Use an 11mm socket (or the appropriate size for your vehicle) to remove the nut securing the sensor.
3. Extract the Sensor: Carefully pull the sensor out without dropping it into the tire.

Step 5: Install the New TPMS Sensor

1. Prepare the New Sensor: Your new TPMS sensor should come with a new nut and washer.
2. Install the Sensor:
   • Insert the Sensor: Push the new sensor through the valve stem.
   • Add the Washer and Nut: Place the washer on the sensor and screw on the nut. Snug it up without overtightening to avoid breaking the stem.

Step 6: Re-seat the Tire Bead

1. Apply Lubrication: Use WD-40 or a similar lubricant around the tire bead to help it slide back into place.
2. Pop the Bead Back On:
   • Lower the Tire: As the vehicle or jack is lowered, listen for the pop indicating the bead has seated properly.

Step 7: Inflate the Tire

1. Add Air: Inflate the tire to the recommended pressure, which is usually found on a sticker inside the driver’s door.

Step 8: Program the New Sensors

1. Use a TPMS Tool: Connect a TPMS programming tool (like the Altel TS501) to your vehicle’s OBD2 port.
2. Reprogram the Sensors: Follow the tool's instructions to register the new sensor ID numbers with your vehicle's computer.
   • Note: If your sensors are clonable, you may transfer the old ID to the new sensor instead.

Conclusion

Replacing TPMS sensors at home is a straightforward process that can save you time and money. By following these steps, you can efficiently change your sensors and keep your vehicle in optimal condition. If you encounter issues or need assistance with programming, consider consulting a professional. Always remember, maintaining your vehicle's tire pressure monitoring system is essential for safe driving.
