Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Tire Pressure Monitor Warning Light
When the tire pressure warning light does not go off, or when it comes on during driving, check tire pressure and adjust as necessary. The warning light should turn off within a few minutes. If the warning light is still on even though the tire pressure is correctly adjusted, the tire could be punctured. Repair as necessary. If the warning light turns on within several hours after adjusting the tire pressure, the tire may have a slow air leak. If the warning light is still on or blinks, there is a malfunction in the TPM system. See appropriate manufacturer service information.
- Facilities or devices that use similar radio wave frequencies are located in the vicinity of the vehicle.
- A radio device of similar frequency is used near the vehicle.
- A lot of snow or ice is stuck to the vehicle, especially around the wheels or wheel housings.
- Tires and wheels are installed that are not equipped with a tire pressure sensor.
- Snow tires or tire chains are used.
- The battery of the sensor has been depleted.
