Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the tires are cool.
Tools Required: Tire pressure gauge, air compressor, tire patch kit (if needed), replacement TPMS sensors (if necessary).

2. Check and Adjust Tire Pressure

Remove valve caps from each tire.
Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate each tire to the manufacturer's recommended pressure, which can be found on the driver's door jamb.
Replace the valve caps securely after adjustment.

3. Inspect Tires for Damage

Visually inspect each tire for cuts, punctures, or bulges.
If a puncture is found, use a tire patch kit to repair or take the tire to a professional for repair.
If any tire is damaged beyond repair, replace it with a new tire.

4. Check TPMS Sensors

If the tire pressure is correct and the light remains on, locate the TPMS sensors in each tire.
Inspect the sensor for any visible damage or corrosion.
If the sensor is malfunctioning, replace it with a new TPMS sensor.

5. Reset the TPMS

After addressing tire pressure and sensor issues, reset the TPMS according to the vehicle's manual.
This often involves using the vehicle's menu system or holding down the TPMS reset button (if equipped).
