Replace a single TPMS (Tire Pressure Monitoring System) sensor on a 2024 Model X Plaid. Tesla uses 433 MHz sensors integrated into the valve stem; sensor auto-pairs to the vehicle once installed and the wheel is rotated.

Warnings

Tools required

Parts

• TPMS sensor, 433 MHz (Tesla Model X 2021+ Refresh spec) × 1 — OEM-equivalent 433 MHz Tesla sensor — confirm part number against VIN before ordering
• TPMS service kit (valve seal, nut, valve core, cap) × 1 — Manufacturer-specified service kit matching the sensor
• Tire valve cap (metal, non-corroding) × 1 — Generic

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with key fob away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even on this non-HV job.
3. Disconnect the 12V low-voltage battery, located in the frunk (similar position to Model S). Remove frunk trim per service manual to access.
4. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage and lethal.
5. If at any point you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
6. Before disconnecting 12V (or if leaving 12V connected for touchscreen access): enable Jack Mode via Controls > Service > Jack Mode to disable air suspension self-leveling.
7. Identify which wheel position has the failed sensor (front-left, front-right, rear-left, rear-right) using the touchscreen TPMS display or scan tool.
8. Loosen lug nuts on the affected wheel slightly while the wheel is still on the ground.
9. Lift vehicle ONLY at the four Tesla-designated jack points using approved pucks. Support with jack stands.

Procedure

1. 1

   Remove the wheel
   With the vehicle safely lifted and supported, fully remove the lug nuts and lift the wheel/tire assembly off the hub. Set the wheel face-down on a clean surface to protect the finish.
2. 2

   Deflate the tire
   Remove the valve cap. Use a valve core tool to remove the valve core and fully deflate the tire. Verify zero pressure with a gauge before breaking the bead.
   ⚠Never break a tire bead on a pressurized tire — risk of explosive bead release.
3. 3

   Break the bead and demount one side
   Using a tire machine, break both beads. You only need to demount the outboard bead far enough to access the TPMS sensor mounted on the valve stem from inside the wheel. Use plastic protectors on the wheel lip to avoid scratching the finished aluminum face.
   ⚠Model X wheels are commonly 20–22 inch with low-profile performance tires — use a tire machine rated for run-flat / low-profile work to avoid sidewall damage.
4. 4

   Remove the failed TPMS sensor
   From inside the wheel, remove the valve stem nut securing the sensor to the wheel. Pull the sensor and valve assembly out through the valve hole. Inspect the wheel valve hole and seat for corrosion or damage.
5. 5

   Install new TPMS sensor
   Install a new service kit (seal, washer, nut, valve core) on the new sensor per the sensor manufacturer's instructions. Insert the sensor through the valve hole, ensuring the sensor body sits flat against the wheel's inner valve seat. Hand-thread the retaining nut from the outside.
   ⚠Always use a fresh service kit — reusing old seals causes slow leaks that won't show up until weeks later.
6. 6

   Torque the sensor retaining nut
   Torque the TPMS retaining nut to the sensor manufacturer's specification (typically 4–8 Nm depending on sensor brand). Do NOT overtighten — overtorquing cracks the sensor housing. Refer to Tesla Service Manual or sensor kit instructions for the exact value.
   ⚠Torque to OEM specification — refer to Tesla Service Manual or the sensor kit's printed spec. Do not use generic lug or bracket torques.
7. 7

   Remount and inflate the tire
   Lubricate beads with tire mounting paste (do not use silicone or petroleum products). Mount the tire back onto the wheel, observing rotation direction if the tire is directional. Seat the beads with controlled inflation, then set pressure to the door-jamb placard spec (typically 42–45 psi cold for Model X — verify on the driver's door jamb sticker).
8. 8

   Balance the wheel
   Spin-balance the wheel/tire assembly. Use stick-on weights on the inner barrel only — do not use clip-on weights on the finished aluminum lip of Model X wheels.
9. 9

   Reinstall the wheel
   Mount the wheel back on the hub, ensuring the mating surface is clean. Hand-thread all lug nuts before applying any torque.
10. 10

    Final lug nut torque
    Lower the vehicle so the tire just contacts the ground (preventing rotation), then torque lug nuts in a star pattern to spec.
    ⚠Star-pattern torque is critical — uneven seating can warp the rotor hat and cause brake pedal pulsation.
    Torque spec

    Wheel Lug Nuts140 Nm (103 lb-ft)

Reassembly

1. Lower the vehicle fully to the ground.
2. Reconnect the 12V battery in the frunk and reinstall any removed trim.
3. Exit Jack Mode (it will auto-exit once the vehicle senses normal ride height, or disable manually via touchscreen).
4. Allow the air suspension to self-level before driving.
5. Reset the TPMS baseline if required: Controls > Service > Tire Pressure Monitor (procedure varies by software version).

Verification

• Drive the vehicle above 15 mph for several minutes — Tesla TPMS sensors auto-pair on the first drive cycle. The TPMS warning light should extinguish within 10–20 minutes of driving.
• Confirm all four tire pressures display correctly on the touchscreen (Controls > Service or the tire pressure card on the main display).
• Verify no TPMS fault, 'Sensor Fault,' or 'Service Required' message persists. If the new sensor does not pair, confirm it is the correct 433 MHz frequency for the 2021+ Model X Refresh — pre-refresh 315 MHz sensors will not work.
• After 50 miles of driving, recheck lug nut torque (140 Nm in star pattern) — Tesla and most aluminum-wheel manufacturers recommend a re-torque check after any wheel removal.
• Inspect the valve stem area with soapy water at full inflation pressure to confirm no leak at the new sensor seal.
