Replace a TPMS (Tire Pressure Monitoring System) sensor on a 2024 Model S Long Range AWD. The sensor is mounted to the valve stem inside each wheel and requires tire dismounting to service.

Warnings

Tools required

Parts

• TPMS sensor (Tesla-spec 433 MHz, 2021+ Model S/X) × 1 — OEM Tesla 433 MHz TPMS sensor — verify exact part by VIN
• Valve stem service kit (seal, nut, cap, core) × 1 — Manufacturer-specified service kit for the sensor being installed

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with the 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 front trunk (frunk) under the nose cowl panel. (Some 2021+ Plaid trims use a 16V Li-ion unit — verify before disconnecting.)
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. Verify which wheel(s) have failed sensors using the touchscreen TPMS readout or a TPMS scan tool.
7. Confirm replacement sensor frequency (433 MHz for 2024 Model S) and check VIN against Tesla parts catalog before opening packaging.
8. Note tire pressure spec on the driver door jamb placard (varies by 19"/21" wheel).

Procedure

1. 1

   Loosen lug nuts
   With the wheel still on the ground, break the lug nuts loose with a 21mm socket. Do not fully remove yet.
2. 2

   Lift the vehicle
   Locate the manufacturer-designated jack point closest to the affected wheel. Place a Tesla-approved jack puck on the floor jack to avoid crushing the pinch weld and to clear the battery pack. Lift and support the vehicle with a jack stand rated for EV curb weight.
   ⚠️Lifting at the wrong point can puncture the HV battery pack floor. Use only Tesla-designated lift points.
3. 3

   Remove the wheel
   Fully remove the lug nuts and lift the wheel off the hub. Set the wheel face-down on a clean surface or wheel cart to protect the finish (especially on 21" Arachnid-style wheels).
4. 4

   Deflate tire and break beads
   Remove the valve cap, then use a valve core tool to remove the valve core and fully deflate the tire. Using a tire machine, break both beads carefully — keep the bead breaker shoe away from the existing TPMS sensor location to avoid damaging it before removal.
   ⚠Striking the sensor with a bead breaker is the #1 cause of damage during this job.
5. 5

   Dismount the tire
   Lubricate the bead with tire mounting soap. Dismount only the upper bead from the wheel — full removal is usually not required. Position the tire so the TPMS sensor is accessible through the opening.
6. 6

   Remove the old TPMS sensor
   From the outside of the wheel, remove the valve stem nut and cap. From the inside, withdraw the old sensor and valve assembly. Inspect the sensor seat in the wheel for corrosion or aluminum oxidation and clean as needed.
7. 7

   Install new TPMS sensor
   Install the new valve seal/grommet from the sensor service kit onto the valve stem. Insert the sensor through the wheel valve hole from the inside. Hand-thread the new valve nut from the outside, then torque to the sensor manufacturer's specification (typically 4–8 Nm depending on stem type) — Torque to OEM specification — refer to Tesla Service Manual. Do not overtighten — the valve stem will shear.
   ⚠Overtightening the valve stem nut on aluminum-body sensors will crack the housing or shear the stem.
8. 8

   Remount and inflate tire
   Lubricate beads, remount the tire on the wheel observing the directional/rotation arrows on the sidewall if applicable. Reinstall the valve core. Inflate to the pressure specified on the door jamb placard (typically 42 psi cold for 19" / 45 psi for 21" — verify on this specific vehicle's placard). Confirm both beads have fully seated.
9. 9

   Balance the wheel
   Spin-balance the wheel/tire assembly. Tesla wheels are sensitive to imbalance — use stick-on weights on the inner barrel of the wheel; do not use clip-on weights on the polished/painted outer lip.
10. 10

    Reinstall the wheel
    Mount the wheel onto the hub. Hand-thread all lug nuts to seat. Lower the vehicle until the tire just contacts the ground.

11. 11

    Final lug torque
    Torque the lug nuts to specification in a star pattern. Re-check torque after the vehicle is fully on the ground.
    ⚠Lug torque is critical on the heavy Model S — under-torqued nuts can loosen; over-torqued can warp the rotor hat.

    Program/relearn the new sensor
    Reconnect the 12V battery. Power up the vehicle. Use a TPMS relearn tool to register the new sensor ID to the correct wheel position, OR drive the vehicle above ~15 mph for 10–20 minutes to allow the auto-locate system to learn the new sensor. Verify all four pressures display correctly on the touchscreen Controls > Service > Tire Pressure (or relevant menu).

Reassembly

1. Confirm valve cap is installed on the new sensor.
2. Reconnect the 12V battery in the frunk and reinstall the nose cowl panel.
3. Clear any residual TPMS warnings on the touchscreen after a successful relearn drive.
4. Reset the cabin tire-pressure display if it still shows the previous fault.

Verification

• All four tire pressures display on the touchscreen and match a manual gauge reading within 1–2 psi.
• No 'TPMS Fault' or 'Service Tire Pressure System' warning after a 15+ minute drive above 15 mph.
• Confirm correct sensor learned to the correct corner (front-left, front-right, rear-left, rear-right) — not just that all four read.
• While the vehicle is on a lift, this is also a good time to check tire rotation interval — Tesla recommends rotation every 6,250 miles due to instant torque and the Model S's heavy curb weight.
