1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a stable surface when checking tire pressure.
•Be cautious when using an air compressor to avoid over-inflation.

Symptoms

•Check tire pressure light illuminated on the dashboard
•Tire pressure readings showing low or inconsistent values
•Vehicle handling feels unstable or different from normal
•Reduced fuel efficiency
•Increased road noise or vibrations

Diagnostic Steps

1
Inspect all tires visually for signs of damage or punctures.
2
Use a tire pressure gauge to measure the pressure of each tire.
3
Check the tire pressure monitoring system (TPMS) using an OBD-II scanner to identify any fault codes.
4
Verify the correct tire pressure for the vehicle as per the manufacturer's specifications.
5
Inspect the TPMS sensors for battery life and proper functioning.

Solution

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, and a portable air compressor.
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 the valve stem caps from each tire's valve.
Sub-step 2: Use the tire pressure gauge to measure the pressure in each tire.
Sub-step 3: Compare the measured pressure to the manufacturer's specifications (found on the driver's door jamb).
Sub-step 4: If tire pressure is low, use the air compressor to inflate the tire to the recommended pressure level.
Sub-step 5: Replace the valve stem caps securely after adjusting the pressure.

3. Inspect and Service TPMS

Sub-step 1: If tire pressure is correct but the light remains illuminated, connect the OBD-II scanner to the vehicle's diagnostics port.
Sub-step 2: Scan for any error codes related to the TPMS and note them for troubleshooting.
Sub-step 3: If necessary, replace any faulty TPMS sensors (typically requires tire dismounting).
Sub-step 4: Reset the TPMS system according to the manufacturer’s instructions.
