Possible Causes

Low Tire Pressure: One or more tires may be significantly under-inflated.
Faulty TPMS Sensor: One or more tire pressure sensors may be malfunctioning.
Damaged Valve Stems: Valve stems may be leaking, causing a loss of tire pressure.
Battery Failure: The battery in the TPMS sensor may be dead (common in older vehicles).
Software Glitches: Occasional software issues can trigger false warnings.

Repair Instructions

1. If Tire Pressure is Low:

Inflate the tires to the recommended pressure using an air compressor.
After inflating, check the pressure again to ensure it is set correctly.
Drive the vehicle for a short distance to allow the system to recalibrate, and check if the warning clears.

2. If Sensors are Faulty:

Tools Required: Tire changing tools, replacement TPMS sensors.
Procedure:
- Remove the wheel from the vehicle using a jack and lug wrench.
- Take the tire off the rim using tire changing tools.
- Replace the faulty TPMS sensor according to the manufacturer's instructions.
- Reinstall the tire and wheel, ensuring everything is torqued to specification.

3. If Valve Stems are Damaged:

Tools Required: Tire changing tools, replacement valve stems.
Procedure:
- Remove the wheel from the vehicle.
- Replace the damaged valve stem with a new one.
- Reinstall the tire and wheel.

4. If Software Issues are Present:

Tools Required: Tesla mobile app or access to Tesla service center.
Procedure:
- If the reset does not work and you suspect a software issue, it may be necessary to contact Tesla support or visit a service center for a software update.

Final Notes

If the TPMS warning persists after checking pressures, replacing sensors, and resetting the system, it is advisable to consult with a Tesla service technician for further diagnostics. Always ensure that tire pressures are maintained regularly to avoid potential safety hazards and improve fuel efficiency.
