SEVEN KEYS TO SUCCESS
The seven keys to success when identifying and servicing vehicles equipped with TPMS:
- TPMS Systems Guide–Featuring detailed vehicle specifications, instructions, reset learning procedures, tools and torque requirements
- Nut Torque Wrench–Proper nut torque is critical to avoid breaking the sensor unit.
- Valve Core Torque Tool–The recommended torque to install valve cores is 3–5 in lbs.
- T-10 Torque Tool–This tool allows the sensor to be removed from the old snap-in valve and installed on a replacement valve. It must be preset at 11.5 inch lbs (1.3 Nm).
- Vehicle-Specific Service Kits and Sensors–Caps, cores, grommets, nuts and washers should be replaced with components that meet OE specifications to restore proper sealing–these components are all available within service kits. Sensors are unique to each vehicle.
- "Learning" Tool–To confirm sensors are working properly before repair, to initiate a new sensor and to facilitate relearning after tire rotation
- Proper Training for All Personnel at Repair Service Centers

Removing and Installing a Clamp-In Sensor
For a quick overview, here are the steps for removal and installation of a clamp-in style TPMS sensor. Or, you can download an illustrated version.
STEP 1: Remove the sealing cap. Remove the valve core using a Schrader Valve Core Torque Tool (Part #20141).
STEP 2: Remove hex nut using hex nut wrench and push sensor into tire, allowing the sensor to drop into tire.
STEP 3: Gently bounce tire to ensure that the sensor falls to the bottom of the tire.
STEP 4: Place wheel on the tire changing machine and break both beads. Make sure that the sensor is at the bottom of the tire.
STEP 5: Place the wheel on the turntable and demount the tire from the wheel according to the tire changer manufacturer's instructions. The sensor can now be safely removed from the tire.
STEP 6: Carefully remove the grommet seal from the sensor using a nonmetallic tool to prevent damage to the aluminum stem. Install a new grommet by hand to prevent tearing the grommet or damaging the stem.
STEP 7: Reinstall valve through the rim hole with the label facing down. To prevent sensor damage, keep sensor alignment level. Do not push down or up on the sensor during torquing.
STEP 8: Hand thread a new hex nut onto the valve stem. Hand tighten until the nut touches the rim.
STEP 9: Use Schrader Torque Wrench (Part #20142). Set to the proper torque. (Varies by vehicle; refer to the Mitchell® TPMS Systems Guide or TIA Relearn Chart for specification.)
STEP 10: Lubricate and mount outside bead of the tire to the rim. Caution: To avoid damage, position sensor 90° from the duck head in the direction of table rotation. The tire should be mounted to the wheel using tire changer manufacturer's instructions.
STEP 11: Use Schrader Valve Core Torque Tool (Part #20141) to install a new electroless nickel-plated valve core into sensor. SEE CAUTION.*
STEP 12: Tire with TPMS is now ready for proper inflation.
*CAUTION: Do not reuse the removed valve core. Always replace with a new electroless nickel-plated valve core. Use of non-electroless nickel-plated cores with aluminum valve stems can result in galvanic corrosion and loss of tire pressure. Tighten core with an approved valve core tool to 0.17–0.37 Nm (1.5–3.3 lbf/in)–DO NOT OVERTIGHTEN.
