why is my Tesla Outback's tire pressure light on after filling the tires?

Solution

1. Preparation

• Gather necessary tools: tire pressure gauge, OBD-II scanner, and TPMS reset tool if needed.
• Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Check and Adjust Tire Pressure

• Sub-step 1: Remove valve caps from each tire, and use the tire pressure gauge to measure the air pressure.
• Sub-step 2: Inflate or deflate tires as needed to match the recommended pressure (typically found on the driver’s door jamb).
• Sub-step 3: Replace valve caps securely after adjusting tire pressures.

3. Reset TPMS

• Sub-step 1: Locate the TPMS reset button, usually near the steering column or under the dashboard.
• Sub-step 2: With the vehicle running and after ensuring all tires are correctly inflated, press and hold the TPMS reset button until the warning light blinks three times.
• Sub-step 3: Drive the vehicle at 25-30 mph for approximately 10 minutes to allow the system to recalibrate.

4. Inspect and Replace TPMS Sensors (if necessary)

• Sub-step 1: If the light remains on, remove the tires from the rims to access the TPMS sensors.
• Sub-step 2: Inspect sensors for any visible damage or corrosion; replace if needed.
• Sub-step 3: Reinstall tires, ensuring proper sealing, and recheck tire pressures.
