⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the engine is off before working on the tires.
•Use caution when handling tires and tools to avoid injury.

Symptoms

•Tire pressure warning light continuously illuminated
•Possible drop in fuel efficiency
•Uneven tire wear
•Reduced handling performance
•Potential for a flat tire if pressure is significantly low

Diagnostic Steps

1
Check tire pressures on all four tires, including the spare, using a reliable tire pressure gauge.
2
Inspect each tire for visible damage such as cuts, punctures, or bulges.
3
Verify if the tire pressure monitoring system (TPMS) sensor is functioning by using an OBD-II scanner to check for any related error codes.
4
Examine the TPMS sensor batteries; if the vehicle is older and under heavy use, the batteries may need replacement.
5
Check for any recent tire changes or rotations that may require TPMS reprogramming.

Solution

Solution

1. Preparation

Gather necessary tools and components.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is turned off.
Safety gear: gloves and safety glasses.

2. Check Tire Pressures

Use a tire pressure gauge to measure the pressure in each tire.
Inflate tires to the manufacturer-recommended pressure specified on the driver’s side door jamb label.

3. Inspect Tires

Visually inspect each tire for signs of damage or wear.
If punctures or significant damage are found, consider replacing the tire or having it repaired at a professional service.

4. Reset TPMS

If tire pressures are correct and no damage is found, reset the TPMS:
1. Turn the ignition to the "On" position (do not start the engine).
2. Locate the TPMS reset button under the steering column or in the glove box.
3. Press and hold the reset button until the TPMS light blinks three times, then release it.
4. Start the engine and let it run for a few minutes to ensure the light turns off.

5. Replace TPMS Sensors (if needed)

If the TPMS warning persists:
1. Remove the tire from the wheel (if necessary) to access the TPMS sensor.
2. Unscrew the sensor from the valve stem and replace it with a new one.
3. Reinstall the tire and ensure it’s sealed properly.
4. Reset the TPMS again to recognize the new sensor.
