Tire Basics: How to Rebuild the TPMS with a TPMS Sensor Service Kit
Your vehicle's Tire Pressure Monitoring System or TPMS measures the air pressure in each tire. It alerts you when your tires lose 25% of its air pressure. Rebuilding your TPMS is advisable when you're having your tires changed or rotated for it to work properly. Using a TPMS Sensor Service kit to rebuild your TPMS will save you labor fees from the tire center.
We listed the tips, tools, and steps you will need to help you with this rebuilding project.
Tools that You'll Need:
- Basic hand tool kit
- Valve core removal tool
- Micro-torque wrench (in-lb)
- TPMS Sensor Service Kit
Safety Tips and Reminders:
- Only reset the TPMS sensors when needed.
- Work in a well-ventilated area and keep a first aid kit handy.
- Do not substitute any of the parts included in the TPMS Service Kit as it may cause problems.
- Always wear recommended safety equipment like closed toed shoes, an industrial-grade dust mask, safety goggles, and gloves.
Step 1: Insert the slotted part of the valve core removal tool over the valve core. Turn the tool clockwise to remove the valve core.
Step 2: Use a ratchet and socket to loosen the TPMS nut by turning it counter-clockwise. Once it's loose, remove the nut from the TPMS.
Step 3: Pull the valve and TPMS sensor through a hole in the rim. Make sure that all the sealing rings come out with the valve and sensor.
Step 4: Put the new sealing rings on the valve stem's sensor side. Carefully push the stem back through the rim's hole, and place the sensor's upper sealing ring.
Step 5: Check if the stem is properly seated in the assembly. Use the new TPMS nut and secure it on the valve stem with your hand tool.
Step 6: Make sure to follow the prescribed torque when using the micro-torque wrench to torque the nut down.
Step 7: Insert the new valve core into the valve core tool's slotted section, and turn it clockwise until it's secure.
Rebuilding the TPMS Sensor with a TPMS Sensor service kit will take about 25 minutes for an expert DIYer and 40 minutes for a beginner. Take your time, and be careful. Have fun with this project!
