⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when the vehicle is lifted.
•Ensure the vehicle is on a flat surface to prevent rolling during tire changes.

Symptoms

•Tire pressure warning light on the dashboard
•Possible visual inspection shows low tire pressure in one or more tires
•Uneven tire wear observed
•Vehicle handling issues (e.g., pulling to one side)
•Reduced fuel efficiency

Diagnostic Steps

1
Inspect each tire visually for signs of damage or low pressure.
2
Use a tire pressure gauge to check the pressure of all tires, including the spare if applicable.
3
Check the tire pressure monitoring system (TPMS) sensor status using an OBD-II scanner.
4
Inspect the TPMS sensors for damage or corrosion, especially if the tires have been recently changed.
5
Reset the TPMS system and see if the warning light returns after driving for a short distance.

Solution

1. Preparation

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

2. Check Tire Pressure

Remove the valve stem caps from all tires.
Use the tire pressure gauge to check the pressure in each tire.
Compare readings to the recommended tire pressure found on the door jamb or owner’s manual.
If pressures are low, inflate the tires to the recommended PSI.

3. Inspect and Replace TPMS Sensors (if necessary)

Remove the tire from the rim if a TPMS sensor needs replacement:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel lug nuts with a socket and remove the wheel.
Access the TPMS sensor:
- Use tire levers to break the bead and separate the tire from the rim.
- Locate and remove the TPMS sensor from the tire.
Replace the TPMS sensor:
- Install a new TPMS sensor, ensuring it is properly seated and secured.
- Reassemble the tire and rim, ensuring the bead is sealed properly.

4. Reset TPMS System

After any adjustments or replacements, reset the TPMS:
- Turn the ignition to the "ON" position without starting the engine.
- Press and hold the TPMS reset button until the TPMS light blinks three times, then release it.
- Drive the vehicle for a short distance to complete the reset.
