⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely lifted and supported before working under it.
•Always check tire pressure when tires are cold for accurate readings.

Symptoms

•Tire pressure warning light on the dashboard
•Inconsistent tire pressure readings on the display
•Warning message indicating low tire pressure
•Possible decrease in vehicle handling or ride comfort
•Tires may show visible signs of deflation or uneven wear

Diagnostic Steps

1
Check the tire pressure on all four tires using a reliable tire pressure gauge.
2
Inspect tires visually for any signs of damage, punctures, or uneven wear.
3
Verify that the tire pressure monitoring system (TPMS) sensors are functioning by checking for any error messages in the vehicle's settings.
4
Review the TPMS system for any stored error codes using the Tesla service menu.
5
Ensure that the tires are inflated to the manufacturer's recommended pressure levels, found on the driver's side door jamb or in the owner's manual.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, OBD-II scanner (if needed), and a tire repair kit.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve caps from all four tires.
2. Use the tire pressure gauge to measure the current tire pressure of each tire.
3. If the pressure is below the recommended level, use an air compressor to inflate the tire to the specified pressure (usually 30-35 PSI for most vehicles).
4. Replace the valve caps securely after adjusting the pressure.

3. Inspect and Replace TPMS Sensors (if necessary)

Sub-steps:
1. If the tire pressure is correct and the warning light remains, the TPMS sensor may be faulty.
2. Remove the tire using a jack and jack stands.
3. Access the TPMS sensor located inside the tire (may require tire dismounting).
4. Inspect the sensor for damage or corrosion, and replace it if necessary.
5. Reinstall the tire and ensure proper torque is applied to the lug nuts (typically 80-100 ft-lbs).

4. Reset the TPMS System

Sub-steps:
1. From the vehicle's touchscreen, go to the "Service" menu.
2. Select "TPMS Reset" and follow the prompts to reset the system.
3. After resetting, ensure that the tire pressures are correct again.
