how to troubleshoot Tesla Model Y Current (2020-present) low tire pressure alert

Solution

1. Preparation

• Gather necessary tools: tire pressure gauge, air compressor, and a TPMS reset tool (if needed).
• Ensure the vehicle is parked on a level surface and that the tires are cool for an accurate pressure reading.

2. Check and Adjust Tire Pressure

• Sub-steps:
  • Remove valve caps from each tire.
  • Use the tire pressure gauge to measure and record the current tire pressures.
  • Compare readings to the recommended tire pressure (found on the door jamb).
  • If the pressure is low, use the air compressor to inflate the tire to the specified level.
  • Replace the valve caps securely after checking.

3. Inspect and Replace TPMS Sensors (if necessary)

• Sub-steps:
  • Remove the tire from the wheel using a tire iron and jack stands.
  • Detach the TPMS sensor from the valve stem.
  • Inspect the sensor for damage or corrosion; replace if necessary with a compatible TPMS sensor.
  • Reinstall the sensor and tire, ensuring proper seating and secure fitment.

4. Reset TPMS

• Sub-steps:
  • Turn on the vehicle and navigate to the settings menu on the touchscreen.
  • Select the "Service" option, then find and select "TPMS Reset."
  • Follow the prompts to reset the system, allowing it to recalibrate based on the new tire pressures.
