⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely supported on a level surface when lifting for tire inspections.

Symptoms

•TPMS warning light illuminated on the dashboard
•Fluctuating or inconsistent tire pressure readings
•A noticeable drop in tire pressure (may require checking with a gauge)
•Possible uneven tire wear
•Vehicle handling issues (such as pulling to one side)

Diagnostic Steps

1
Check the current tire pressure using a reliable tire pressure gauge.
2
Inspect all tires visually for signs of damage, such as punctures or bulges.
3
Verify that the TPMS sensors are functioning by using an OBD-II scanner to check for error codes related to the TPMS.
4
Ensure that all tires, including the spare (if equipped with a sensor), are inflated to the manufacturer-recommended pressure.
5
Reset the TPMS system following the vehicle owner's manual instructions.

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, and possibly a jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Check Tire Pressure

Use the tire pressure gauge to measure the pressure in each tire.
Compare the readings to the manufacturer’s recommended tire pressure, which can typically be found on the driver’s side door jamb.
Inflate any tires that are below the recommended pressure using an air compressor.

3. Inspect Tires for Damage

Carefully examine each tire for visible damage such as cuts, punctures, or sidewall bulges.
If damage is found, replace the affected tire or have it repaired by a professional.

4. Verify TPMS Sensor Functionality

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Check for any stored TPMS-related error codes that could indicate sensor failure or malfunction.
Address any error codes by replacing faulty sensors if necessary.

5. Reset TPMS

Follow the specific procedure for resetting the TPMS as outlined in your vehicle’s owner manual. This usually involves turning the ignition on and off in a specific sequence or pressing a reset button located under the steering column.
