⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked on a flat surface and the engine is off before starting work.
•Always wear safety goggles when working with tires and tire-changing equipment.
•Ensure the vehicle is securely lifted and stable when working under it.

Symptoms

•Tire pressure warning light is continuously illuminated on the dashboard
•Possible uneven tire wear
•Vehicle may feel unstable or bumpy while driving
•Decreased fuel efficiency
•Inconsistent or poor handling characteristics

Diagnostic Steps

1
Check Tire Pressure: Use a tire pressure gauge to measure the air pressure in all tires including the spare.
2
Inspect Tires: Visually inspect each tire for signs of damage, punctures, or visible leaks.
3
Reset TPMS: Attempt to reset the Tire Pressure Monitoring System (TPMS) using the vehicle's reset procedure.
4
Scan for Error Codes: Use an OBD-II scanner to check for any error codes related to the TPMS.
5
Inspect TPMS Sensors: Check the condition of the TPMS sensors in each wheel for functionality and battery life.
6
Check for Tire Rotation: Ensure that the tires have been rotated recently, as improper rotation can affect TPMS readings.

Solution

Solution

1. Preparation

Gather Tools: Tire pressure gauge, OBD-II scanner, jack and jack stands, tire patch kit (if necessary).
Safety Warning: Ensure the vehicle is parked on a flat surface and the engine is off before starting work.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve caps from all tires.
2. Use the tire pressure gauge to measure each tire's pressure.
3. Inflate or deflate the tires to match the manufacturer's recommended pressure (usually found on the driver’s door jamb).
4. Replace all valve caps securely.

3. Inspect and Repair Tires

Sub-steps:
1. Examine each tire for visible damage, such as cuts or punctures.
2. If a puncture is found, use a tire patch kit to repair it or replace the tire if damage is severe.
3. Ensure all tires are properly seated on the rims.

4. Reset the TPMS

Sub-steps:
1. Turn the vehicle's ignition to the "On" position without starting the engine.
2. Press and hold the TPMS reset button (usually located under the steering column or in the glove box) until the TPMS light blinks three times.
3. Start the vehicle and allow it to run for a few minutes to verify that the light resets.

5. Replace TPMS Sensors (if necessary)

Sub-steps:
1. If the TPMS sensors are non-functional, remove the tires from the wheels using a tire changer.
2. Replace the faulty sensors with new ones, ensuring they are compatible with the vehicle.
3. Reinstall the tires, balancing them as necessary.
