Resetting the Tire Pressure Sensor for the 2022 Lexus NX 350
The tire pressure monitoring system (TPMS) in the 2022 Lexus NX 350 is designed to alert drivers when tire pressure is too low. However, after adjusting tire pressure, the TPMS light may continue to flash. This indicates that the system needs to be reset to recognize the new tire pressure levels. Here are the steps to reset the tire pressure sensor effectively.
Steps to Reset the Tire Pressure Sensor
- Ensure that all tires are inflated to the recommended pressure as specified in the owner’s manual or the tire pressure table.
- Turn the ignition key to the “ON” position without starting the engine.
- Locate the TPMS reset button, usually found beneath the steering wheel or on the dashboard.
- Press and hold the TPMS reset button until the TPMS light blinks three times and then turns off.
- Start the engine and drive the vehicle for about 10 minutes at a speed of 50 mph or more to allow the system to recalibrate.
Tire Pressure Monitoring System Light Flashing
If the TPMS light continues to flash after resetting, it may indicate a malfunction in the system. Here are some common reasons for a flashing TPMS light:
| Issue | Description |
|---|---|
| Low Tire Pressure | One or more tires are under-inflated. |
| Faulty Sensor | A tire pressure sensor may be damaged or malfunctioning. |
| Battery Issue | The battery in one of the tire pressure sensors may need replacement. |
| System Malfunction | The TPMS may have a fault that requires professional diagnosis. |
If the light remains flashing after following the reset steps, it is advisable to consult a certified Lexus technician for further inspection.
Importance of Maintaining Proper Tire Pressure
Maintaining proper tire pressure is critical for the overall performance and safety of your 2022 Lexus NX 350. Incorrect tire pressure can lead to a range of issues, including decreased fuel efficiency, uneven tire wear, and compromised handling. Under-inflated tires can cause the vehicle to consume more fuel, while over-inflated tires can lead to a harsh ride and increased risk of blowouts. Therefore, regular monitoring of tire pressure is essential.
Benefits of Proper Tire Pressure
- Enhanced Safety: Properly inflated tires improve traction and handling, reducing the risk of accidents.
- Better Fuel Efficiency: Maintaining the correct tire pressure can enhance fuel economy, saving you money at the pump.
- Extended Tire Life: Correct tire pressure helps prevent uneven wear, extending the lifespan of your tires.

How to Check Tire Pressure
Checking the tire pressure of your NX 350 is a straightforward process that can be done at home or at a service station. Here’s how to do it:
- Purchase a reliable tire pressure gauge, either digital or analog.
- Ensure that the tires are cold, as pressure can increase with heat from driving.
- Remove the valve cap from the tire you wish to check.
- Press the tire pressure gauge firmly onto the valve stem to get a reading.
- Note the PSI reading displayed on the gauge.
- Replace the valve cap securely after checking.
Useful Tips for Maintaining Tire Pressure
To ensure that your tires remain properly inflated, consider the following tips:
- Regular Inspections: Check your tire pressure at least once a month and before long trips.
- Know the Recommended Pressure: Refer to the owner’s manual or the sticker inside the driver’s door for the correct tire pressure.
- Monitor Temperature Changes: Tire pressure can drop in colder weather, so check more frequently during winter months.
- Use a Quality Gauge: Invest in a good tire pressure gauge for accurate readings.
- Don’t Forget the Spare: Ensure that your spare tire is also properly inflated, as it can be critical in emergencies.
By following these guidelines, you can help ensure that your 2022 Lexus NX 350 operates safely and efficiently, maximizing both performance and tire longevity.
