⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety glasses when working with tires and inflating them to avoid injury.
•Ensure the vehicle is securely lifted before working on tires to prevent accidents.

Symptoms

•Tire pressure monitoring system (TPMS) warning light illuminated on the dashboard
•Decreased handling or stability while driving
•Possible audible alert indicating low tire pressure
•Increased tire wear or uneven tread patterns
•A noticeable drop in fuel efficiency or range

Diagnostic Steps

1
Check the tire pressure of all four tires using a reliable tire pressure gauge.
2
Inspect the tires visually for any visible damage such as punctures, cuts, or bulges.
3
Verify the TPMS sensor function with a diagnostic tool or OBD-II scanner.
4
Look for any recent changes in temperature that might affect tire pressure.
5
Check the vehicle's settings to confirm the tire pressure specifications are correctly set.
6
Inspect the valve stems for leaks or damage.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the tires are cold (not driven for at least 3 hours).

2. Check and Adjust Tire Pressure

Tools Required: Tire pressure gauge, air compressor.
Use the tire pressure gauge to measure the pressure in each tire.
Compare the measured pressure with the recommended pressure found on the driver’s door jamb.
Inflate tires to the correct pressure using an air compressor if necessary.
Replace the valve stem caps.

3. Inspect and Repair Tires

Tools Required: Tire repair kit (if applicable), jack, lug wrench.
If any tires have visible damage, use the jack to lift the vehicle and remove the damaged tire with the lug wrench.
Inspect for punctures or other damage that requires repair or replacement.
If there is a puncture, follow the tire repair kit instructions to seal the puncture or take it to a professional tire service.

4. Reset the TPMS

Tools Required: OBD-II scanner (optional).
After adjusting the tire pressures, start the vehicle and check if the TPMS warning light turns off.
If the warning persists, use the OBD-II scanner to reset the TPMS system or follow the vehicle’s manual instructions for manual reset.
