How to reprogram TPMS sensors in Lexus?
The Tire Pressure Monitoring System (TPMS) is a critical safety feature in modern vehicles, including Lexus models. It alerts drivers when tire pressure is too low, helping to prevent accidents and improve fuel efficiency. If you've replaced your tires, installed new TPMS sensors, or experienced a system malfunction, reprogramming the sensors may be necessary. In this guide, we'll walk you through the steps to reprogram TPMS sensors in your Lexus.
What You Need to Know Before Reprogramming
Before diving into the reprogramming process, it's essential to understand a few key points about TPMS sensors:
- Each TPMS sensor has a unique ID that must be registered with your vehicle's onboard computer.
- Reprogramming may require a specialized TPMS tool or scanner, depending on your Lexus model.
- Ensure your tires are inflated to the recommended pressure levels before starting the process.
Steps to Reprogram TPMS Sensors in a Lexus
Follow these steps to reprogram the TPMS sensors in your Lexus. Note that the exact process may vary slightly depending on the model and year of your vehicle.
- Step 1: Gather the Necessary Tools
You'll need a TPMS reset tool or scanner compatible with Lexus vehicles. These tools can be purchased online or borrowed from an auto parts store.
- Step 2: Locate the OBD-II Port
The OBD-II port is typically located under the dashboard on the driver's side. This is where you'll connect the TPMS tool.
- Step 3: Turn on the Ignition
Insert your key and turn the ignition to the "ON" position without starting the engine. This powers the vehicle's electronic systems.
- Step 4: Use the TPMS Tool
Follow the instructions provided with your TPMS tool to scan and register the sensor IDs. The tool will communicate with the vehicle's computer to update the sensor information.
- Step 5: Verify the Reprogramming
After reprogramming, check the TPMS warning light on your dashboard. If the light turns off, the process was successful. If it remains on, repeat the steps or consult a professional mechanic.
When to Seek Professional Help
While reprogramming TPMS sensors can often be done at home, there are situations where professional assistance may be necessary:
- If you don't have access to a TPMS tool or scanner.
- If the TPMS warning light remains on after multiple attempts to reprogram.
- If you're unsure about the process or encounter unexpected issues.

Frequently Asked Questions
Can you program TPMS sensors yourself?
Follow the on-screen instructions on the TPMS tool to program each sensor to the vehicle's TPMS system. This process may involve inputting new sensor IDs or copying the old sensor's ID to the new sensor. Top of the line scan tools like Autel allow for "auto creation" where it takes care of all this automatically.
Why is my TPMS light on if my tires aren't flat?
If in any case the pressure is not optimum, then the computer will turn on the tire pressure light. However, sometimes the light is trying to indicate other signals apart from the tire pressure. For instance, extreme cold or hot temperatures can also be the reason why your TPMS light turns on.
Does AutoZone program TPMS sensors?
If you have symptoms or it's time to replace your TPMS sensors, find the right match at AutoZone. We carry options that work for most makes and models, and our friendly staff can offer trustworthy advice on how to get it done, including programming.
Do TPMS sensors need to be reprogrammed?
These sensors must be programmed with the proper protocol/application information for the vehicle before they can be installed in the tire, and then must be relearned to the vehicle. Unfortunately, some shops overlook the necessary relearn step mistakenly believing the sensor programming did the trick.
Can I reset my TPMS myself?
Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait about 20 minutes for the sensor to refresh. You will find the tire pressure monitor reset button under the steering wheel. Refer to your vehicle's owner's manual if you can't find it.
Can you relearn TPMS sensors without a scan tool?
Turn into the run. Position. You're gonna press the lock and unlock buttons on your remote soon as you hear the horn honk you'll see on the dash it'll say tire learning active. Around to the front of
How do I reprogram my Lexus TPMS?
The easiest way to reset your Lexus' TPMS is the same as with many manufacturers: Once the tires are pressurized, drive for about 25 miles or around 50 mph for 10 minutes and it should reset the next time you turn on the car.
Why is my tire pressure light on when my tires are fine in Lexus?
It's possible that the car's Tire Pressure sensor could fail because of its age. If that happens, it needs to be fixed when you see it.
How to permanently turn off TPMS light?
One of the solutions to “turn off” the TPMS light is to cover it with black tape. It is a crude method but preferred by many as it does not require tinkering with the vehicle's wires or ECU.
How long do Lexus TPMS sensors last?
Most TPMS sensors run on batteries that are built into the sensor and these batteries are not replaceable. The life expectancy of the lithium ion batteries in a TPMS sensor is anywhere from 5-10 years.
