Why the Tire Pressure Light is Still On After Filling Tires in a Lexus
If your tire pressure light is still on after filling your tires in a Lexus, there are a few potential reasons for this:
1. Sensor Calibration:
– The tire pressure light may remain on for at least 15 minutes after filling the tires while driving, as the TPMS system recalibrates the readings. However, if the light remains on after this time, there may be an issue with the TPMS system.
– It’s recommended to drive your vehicle for at least 10-15 minutes at speeds of 30 mph or higher after filling your tires to allow the TPMS sensor to recalibrate and for the tire pressure light to turn off.
2. Sensor Fault or Low Battery:
– If one or more of the TPMS sensors are faulty or if the battery in one or more sensors is low, it can cause inaccurate readings and trigger the tire pressure light to stay on, even if the tires are properly inflated.
3. Tire Leak:
– If there is a slow leak in one or more tires, the pressure may drop below the recommended level, even if the tires were recently filled with air. This can cause the tire pressure light to stay on.
4. TPMS Issue:
– If you’ve filled your tires, but the light still won’t turn off, and you’ve used a pressure gauge to check the tire pressure and found it to be fine, then the TPMS itself may have an issue.
What to Do Next
If your tire pressure light remains on after filling your tires, it’s important to take the following steps:
1. Check Tire Pressure: Use a tire pressure gauge to check the actual pressure in each tire to ensure they are inflated to the recommended level.
2. Drive the Vehicle: Drive the vehicle for at least 10-15 minutes at speeds of 30 mph or higher to allow the TPMS sensor to recalibrate.
3. Consider TPMS Inspection: If the light remains on after following these steps, it may be necessary to have the TPMS system inspected by a qualified technician to identify any potential issues with the sensors or the system itself.
In summary, the tire pressure light in a Lexus may remain on due to sensor calibration, sensor faults, tire leaks, or TPMS issues. It’s important to ensure the tires are properly inflated and to follow the recommended recalibration process before seeking further assistance if the issue persists.

Is it OK to drive with TPMS light on?

As we mentioned earlier, a tire pressure light is a warning, not a command, so you don’t need to pull over immediately if you see it come on. However, driving on underinflated tires can be dangerous and can cause a variety of problems, including poor handling, reduced fuel efficiency, and increased tire wear.

Why is my TPMS light on when my tires are fine?

TPMS malfunction: If the TPMS itself is malfunctioning, the light may come on even if your tire pressure is normal. If you see the tire pressure light and your tires seem properly inflated, it’s a good idea to have the TPMS checked by a mechanic.

How long does it take for the tire pressure light to go off after filling tires?

After about 20 minutes of driving, the air will often warm up and expand, restoring proper pressure in your tires. If the light stays on after 20 minutes on the road, you should add air to your tires as needed to restore the proper pressure. Low tire pressure is hazardous for your vehicle regardless of the cause.

If you’ve inflated your tires to the proper air pressure, but the warning light stays on, you may have a leak or there’s a problem with the TPMS in one or more of your tires. It’s simple enough to check if there’s a leak in a tire. Just use your tire gauge to recheck the air pressure in all your tires.
