⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely lifted before working on tires.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible uneven tire wear
•Decreased fuel efficiency
•Vehicle may feel unstable during driving
•Tire pressure readings may show low values on the dashboard display

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to check for additional tire-related codes.
2
Inspect each tire visually for damage, punctures, or irregular wear.
3
Use a tire pressure gauge to check the actual tire pressures against the manufacturer's recommended values.
4
Verify the functionality of the tire pressure monitoring system (TPMS) sensors by resetting the system.
5
Check for any leaks or damage to the valve stems.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and glasses.

2. Check Tire Pressures

Tools Required: Tire pressure gauge
Remove the valve caps from each tire.
Use the tire pressure gauge to measure the tire pressure of each tire.
Compare the readings with the recommended tire pressure values located on the driver’s side door jamb or in the owner’s manual.
Inflate or deflate the tires as necessary to match the recommended pressure.

3. Inspect and Replace TPMS Sensors (if needed)

Tools Required: Tire iron, jack, TPMS tool (if available)
Loosen the lug nuts on the tire that is suspected of having a faulty TPMS sensor.
Use the jack to lift the vehicle and remove the wheel.
Inspect the TPMS sensor for damage or corrosion.
If replacement is necessary, unclip the old sensor and install the new one according to the manufacturer’s instructions.
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.

4. Reset the TPMS System

Tools Required: OBD-II scanner (if needed)
Start the vehicle and navigate to the settings menu on the dashboard display.
Locate the TPMS reset option and select it.
Follow on-screen instructions to complete the reset. If using a scanner, connect it and follow the prompts to reset the TPMS.

5. Final Checks

Tools Required: Tire pressure gauge
After completing the reset, use the tire pressure gauge again to verify that all tires are at the correct pressure.
Replace all valve caps securely.
