Diagnostic Steps

1
Check the tire pressure of all tires using a tire pressure gauge.
2
Inspect each tire visually for any signs of damage or punctures.
3
Verify the recommended tire pressure from the owner’s manual or the driver’s door jamb.
4
Check the spare tire for proper inflation.
5
Inspect the tire pressure monitoring system (TPMS) sensor for faults.

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and repair kit (if needed).
Ensure the vehicle is parked on a flat surface and the tires are cold for accurate pressure readings.

2. Adjust Tire Pressure

Remove the valve cap from each tire.
Use the tire pressure gauge to measure the pressure in each tire.
If the pressure is below the recommended level:
- Use an air compressor to inflate the tire to the correct pressure.
- Check the pressure again with the gauge to confirm it is at the correct level.
Replace the valve cap securely on each tire.

3. Inspect and Repair (if needed)

If any tire shows signs of damage or punctures:
- Remove the tire from the vehicle using a jack and lug wrench.
- Inspect the tire thoroughly for punctures or sidewall damage.
- If a puncture is found, follow the repair procedure or replace the tire if necessary.
If the TPMS sensor is faulty, replace the affected sensor.
