How do you fix the tire pressure sensor on a Lexus?
If your Lexus is displaying a tire pressure warning light, it's likely due to an issue with the tire pressure sensor. Fortunately, fixing this problem is a relatively straightforward process that you can often do yourself. In this article, we'll guide you through the steps to diagnose and repair a malfunctioning tire pressure sensor on your Lexus.
Diagnosing the Tire Pressure Sensor Issue
The first step is to determine the cause of the tire pressure warning light. This could be due to a variety of reasons, including a faulty sensor, low tire pressure, or a problem with the tire pressure monitoring system (TPMS) itself. To diagnose the issue, you'll need to use a TPMS diagnostic tool or take your Lexus to a mechanic.
Replacing the Tire Pressure Sensor
If the diagnostic test reveals a faulty tire pressure sensor, you'll need to replace it. Here's how to do it:
- Locate the tire pressure sensor, which is usually located inside the tire or on the wheel rim.
- Carefully remove the sensor, taking note of its orientation and any wiring connections.
- Install the new sensor, making sure it's properly aligned and connected.
- Use a TPMS diagnostic tool to ensure the new sensor is functioning correctly.
- Reset the TPMS system according to the manufacturer's instructions.
After replacing the tire pressure sensor and resetting the TPMS system, the warning light should turn off, and your Lexus should be back to normal operation.
Maintaining Proper Tire Pressure
To prevent future issues with the tire pressure sensor, it's important to maintain the proper tire pressure in your Lexus. Check the recommended tire pressure, which can be found in your owner's manual or on the driver's side door jamb sticker, and adjust the pressure accordingly.
By following these steps, you can effectively diagnose and repair a malfunctioning tire pressure sensor on your Lexus, ensuring your vehicle's safety and performance.

How do you fix the tire pressure on a Lexus?
Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait 20 minutes for the sensor to refresh. The tire pressure monitor reset button is usually located beneath the steering wheel.
Can I reset my tire sensors myself?
Once you have properly inflated your tires, the tire pressure light should automatically go off. However, if it doesn't, there are a few different things that you can try: Drive at or above 50 mph to reset the sensor for 10 minutes. This causes your sensor to reset the next time you turn on your car.
How long do Lexus TPMS sensors last?
