⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely lifted and supported before working under it.
•Allow tires to cool before measuring tire pressure to ensure accurate readings.

Symptoms

•Dashboard warning light for low tire pressure illuminated
•Tire pressure readings below the recommended PSI
•Possible uneven tire wear
•Vehicle may feel unstable or have a rough ride
•Increased fuel consumption

Diagnostic Steps

1
Check tire pressures using a tire pressure gauge for all four tires, including the spare if equipped with TPMS.
2
Inspect each tire visually for signs of damage, punctures, or excessive wear.
3
Verify that the TPMS sensor is functioning by using an OBD-II scanner to check for any error codes related to the TPMS.
4
Inspect the TPMS sensors for corrosion or damage, especially if the vehicle has recently experienced tire changes.
5
Reset the TPMS following the manufacturer's instructions to see if the warning light reactivates.

Solution

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure you have a digital tire pressure gauge, a jack, jack stands, and a tire inflator.
Safety warning: Ensure the vehicle is parked on a flat surface and the engine is off.

2. Tire Pressure Check

a. Remove the valve stem caps from each tire.
b. Use the tire pressure gauge to measure the PSI of each tire.
c. Compare the readings to the manufacturer's recommended pressure, which can usually be found on the driver's side door jamb or in the owner's manual.

3. Inflate or Replace Tires

a. If any tire is under-inflated, use a tire inflator to bring it up to the recommended PSI.
b. If a tire shows signs of damage or is excessively worn, consider replacing it.

4. Inspect and Replace TPMS Sensors (if necessary)

a. Remove the tire from the wheel to access the TPMS sensor.
b. Inspect the sensor for damage; replace if necessary.
c. Reinstall the tire onto the wheel, ensuring proper seating.

5. Reset the TPMS

a. Start the vehicle and locate the TPMS reset button (usually found under the steering wheel or in the glove box).
b. Press and hold the reset button until the TPMS warning light blinks three times.
c. Drive the vehicle for a short distance to allow the system to recalibrate.
