Replace a TPMS (Tire Pressure Monitoring System) sensor on a 2024 Model Y Long Range AWD. The sensor is integrated with the valve stem and mounts inside the wheel; this requires tire dismount/remount and rebalancing.

Warnings

Tools required

Parts

• TPMS sensor (Bluetooth 433 MHz type for 2021+ Model Y/3) — manufacturer-specified × 1 — OEM TPMS sensor for 2021+ Model Y; verify part number against VIN before purchase
• Replacement valve service kit (seal, nut, cap, core) — typically supplied with sensor × 1 — Included with OEM sensor kit
• Tire valve stem grommet/seal × 1 — Per OEM sensor service kit

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 under the rear cargo area trim on 2024 Model Y) before lifting. For a tire-only TPMS job some technicians skip this; if you do, at minimum enable Service Mode → Tow Mode and disable Sentry/cabin overheat to prevent the car from waking and dropping off jack stands.
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. Identify which wheel's sensor has failed using the touchscreen (Controls → Service → Tire Pressure) — note the current pressures and the failed position.
7. Loosen the lug nuts on the affected wheel approximately 1/4 turn while the wheel is still on the ground.
8. Lift the vehicle ONLY at the factory-designated jack points using a Tesla-approved puck. Support with jack stands.

Procedure

1. 1

   Remove the wheel
   Fully unscrew and remove the lug nuts. Lift the wheel straight off the hub. Inspect the hub face and lug studs for corrosion or damage. Place the wheel face-down on a soft surface to protect the finish.
2. 2

   Deflate the tire and break both beads
   Remove the valve cap and use a valve core tool to fully deflate the tire. Mark the tire's position relative to the valve stem with chalk so it can be remounted in the same rotational orientation (preserves balance). Break both inner and outer beads on the tire machine using non-marring shoes.
   ⚠Aluminum wheel — use plastic mount/demount protectors and rim guards on the bead breaker.
3. 3

   Demount the tire
   Mount the wheel on the tire machine and demount the upper bead, then the lower bead, taking care not to gouge the rim. The TPMS sensor is mounted to the inside of the rim at the valve stem hole — be aware of its location when working the bead near the valve so the demount tool does not strike the sensor.
4. 4

   Remove the old TPMS sensor
   From inside the rim, unscrew the valve stem nut on the outside of the rim and withdraw the sensor assembly through the valve hole into the inside of the wheel. Inspect the rim's valve seat for corrosion and clean with a non-abrasive pad if needed.
5. 5

   Install the new TPMS sensor
   Verify the new sensor is the correct Tesla-spec Bluetooth TPMS for a 2024 Model Y. Install the new grommet/seal from the service kit. Position the sensor inside the rim with the valve stem protruding through the valve hole, then thread the new retaining nut onto the valve stem from the outside. Tighten the valve stem retaining nut to the sensor manufacturer's specification — typically a low value (around 4 Nm / 35 in-lb) — refer to the Tesla Service Manual / sensor instructions. DO NOT overtighten; overtorque will crack the sensor housing.
   ⚠Do NOT use the bracket/sensor torque values from the general torque chart for the valve stem nut — it is much lower. Follow the value supplied with the sensor or Tesla Service Manual.
6. 6

   Remount the tire
   Apply tire mounting lubricant to both beads. Align the chalk mark to the valve stem and mount the lower then upper bead, keeping the demount/mount head clear of the new sensor. Inflate the tire to seat both beads (pop), then set pressure to the door jamb specification (typically 42 psi cold for Model Y Long Range — verify on the B-pillar placard). Install a new valve core if supplied, and the new valve cap.
7. 7

   Balance the wheel
   Balance the wheel/tire assembly on a balancer using stick-on weights placed where the original weights were located (inboard of the spoke face on Model Y aero/sport wheels). Do not use clip-on weights on the rim flange — they will damage the wheel finish.
8. 8

   Reinstall the wheel
   Clean the hub mating face. Lift the wheel onto the hub, start all lug nuts by hand to prevent cross-threading, then snug them in a star pattern.
9. 9

   Torque the lug nuts
   Lower the vehicle until the tire just contacts the ground (loaded but not full weight), then final-torque the lug nuts in a star pattern to the verified specification.
   ⚠️Under- or over-torqued lug nuts can cause wheel separation. Use a calibrated torque wrench — never an impact gun for final torque.

Reassembly

1. Lower the vehicle fully to the ground.
2. Reconnect the 12V low-voltage battery if it was disconnected, and reinstall any trim removed for access.
3. Wake the vehicle and confirm it powers up normally with no persistent faults on the dash.

Verification

• On the touchscreen, navigate to Controls → Service → Tire Pressure and confirm all four tire pressures eventually read live values (the new sensor may take a few minutes or a short drive to report).
• Drive the vehicle above ~15 mph for 5-10 minutes. The TPMS warning should self-clear once the new sensor is learned. If it does not, use a TPMS programming tool to read the new sensor ID and program/relearn it to the correct corner via Tesla's relearn procedure.
• Recheck cold tire pressures the next morning and adjust to the door-jamb spec (typically 42 psi for Model Y Long Range — verify placard).
• Note: Tesla recommends tire rotation every 6,250 mi on Model Y due to high curb weight and instant torque — log this service date and consider scheduling a rotation if due.
