⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a level surface to prevent accidents while inflating tires.
•Use caution when handling tires and wheels to avoid injury.

Symptoms

•Tire pressure warning light is illuminated on the dashboard
•Tires appear visibly under-inflated
•Vehicle handling feels unstable or different
•Possible decrease in fuel efficiency
•Increased tire wear observed

Diagnostic Steps

1
Visually inspect all tires for obvious signs of under-inflation or damage.
2
Use a tire pressure gauge to check the pressure of each tire against the manufacturer's recommended PSI.
3
Check the TPMS sensor status using an OBD-II scanner.
4
Inspect the TPMS warning light functionality by turning the ignition on (without starting the engine) to see if the light illuminates and then turns off.
5
Look for any leaks around the valve stems or bead area of the tires.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is turned off.

2. Inflate Tires

Using a tire inflator, fill each tire to the recommended PSI as indicated on the driver’s side door jamb.
Recheck the pressure with a tire pressure gauge to ensure accuracy.

3. Reset TPMS

Locate the TPMS reset button (usually found under the steering column or in the glove compartment).
Press and hold the reset button until the TPMS light blinks three times, then release it.
Start the vehicle and allow it to run for a few minutes, ensuring the light remains off.

4. Inspect and Replace TPMS Sensors (if necessary)

If the tire pressure is correct but the light remains on, remove the tires from the rims to access the TPMS sensors.
Inspect the sensors for damage or corrosion; replace if necessary.
Reinstall the tires and ensure proper sealing at the rim.
