⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked on a flat surface to prevent accidental movement.
•Allow tires to cool before measuring pressure to get an accurate reading.

Symptoms

•Low tire pressure warning light is illuminated on the dashboard
•Tire pressure may be visibly low in one or more tires
•Possible uneven tire wear
•Decreased fuel efficiency
•Warning message displayed on the vehicle's information screen (if equipped)

Diagnostic Steps

1
Check all tire pressures using a reliable tire pressure gauge.
2
Inspect each tire for visible signs of damage, punctures, or leaks.
3
Verify that the tire pressure monitoring system (TPMS) sensor is functioning by using an OBD-II scanner to check for error codes.
4
Reset the TPMS system using the reset button or through the vehicle's settings menu, if applicable.
5
Inspect the TPMS sensors for battery life or any corrosion on the sensor contacts.
6
Review the vehicle's owner's manual for the correct tire pressure specifications and reset procedures.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the tires are cool.
Tools Required: Tire pressure gauge, OBD-II scanner, TPMS reset tool (if needed).

2. Check Tire Pressures

Remove valve stem caps from each tire.
Use the tire pressure gauge to measure the pressure in each tire.
Inflate each tire to the manufacturer's recommended pressure (usually found on a sticker inside the driver's door).

3. Inspect Tires

Visually inspect each tire for any punctures, cuts, or abnormal wear patterns.
If damage is found, repair or replace the tire as necessary.

4. Reset TPMS

Locate the TPMS reset button, typically found under the steering wheel or in the glove compartment.
With the ignition on, press and hold the reset button until the TPMS light blinks three times, then release it.
Drive the vehicle for a short distance to complete the reset process.

5. Check TPMS Sensors

If the light remains on after resetting, use an OBD-II scanner to check for TPMS-related error codes.
If the codes indicate a sensor failure, replace the affected TPMS sensor.
Ensure to reprogram the new sensor to the vehicle's system following the manufacturer's instructions.
