⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath it.

Symptoms

•Tire pressure warning light is flashing
•Possible decrease in tire pressure
•Onboard computer may display tire pressure readings
•Vehicle may handle differently or feel unstable
•Check engine light may illuminate in some cases

Diagnostic Steps

1
Check Tire Pressure: Use a tire pressure gauge to measure the pressure in all four tires, ensuring they are inflated to the manufacturer's specifications.
2
Inspect Tires for Damage: Visually examine each tire for punctures, cuts, or visible damage that may cause air loss.
3
Check TPMS Sensor Function: Use an OBD-II scanner to check for any TPMS-related error codes.
4
Reset TPMS System: Follow the vehicle's manual to reset the TPMS system after correcting any tire pressure issues.
5
Inspect TPMS Valves: Check the TPMS valve stems for leaks or damage, which may prevent accurate readings.
6
Test Battery in TPMS Sensors: If equipped, check the battery condition of the individual TPMS sensors, as they may need replacement if they are low.

Solution

Solution

1. Preparation

Tools Required: Tire pressure gauge, OBD-II scanner, jack and jack stands, wrench set.
Ensure the vehicle is parked on a level surface and the tires are cool before measuring pressure.

2. Adjust Tire Pressures

Sub-steps:
1. Remove the valve cap from each tire.
2. Using the tire pressure gauge, check the pressure of each tire.
3. Inflate or deflate tires as needed to match the recommended pressure (found on the driver's door jamb).
4. Replace the valve caps securely.

3. Reset TPMS

Sub-steps:
1. Locate the TPMS reset button, usually found beneath the steering column or in the glove box.
2. Turn the ignition to the "ON" position without starting the engine.
3. Press and hold the TPMS reset button until the TPMS indicator blinks three times, then release it.
4. Start the vehicle and allow it to run for a few minutes to verify the reset was successful.

4. Replace TPMS Sensors (if necessary)

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the wheel from the affected tire.
3. Detach the TPMS sensor from the valve stem using a wrench.
4. Install the new TPMS sensor by reversing the removal steps and ensure it is securely fastened.
5. Reinstall the wheel and tighten lug nuts to the manufacturer's torque specifications.
