How to Reset and Relearn the TPMS of Toyota Crown in All Generations
The Toyota Crown, a flagship luxury sedan, has been a symbol of automotive excellence since its introduction in 1955. One of the many advanced features in modern Crown models is the Tire Pressure Monitoring System (TPMS). This system ensures optimal tire pressure, enhancing safety, fuel efficiency, and tire longevity. In this comprehensive guide, we’ll explore how to reset and relearn the TPMS in all generations of the Toyota Crown, providing you with expert knowledge to maintain your vehicle’s performance.
Understanding TPMS in Toyota Crown
Before diving into the reset and relearn procedures, it’s crucial to understand what TPMS is and how it functions in Toyota Crown vehicles.
What is TPMS?
TPMS is an electronic system designed to monitor the air pressure inside pneumatic tires. It reports real-time tire pressure information to the driver, usually through a gauge or a low-pressure warning light.
Types of TPMS in Toyota Crown
Toyota Crown models typically use one of two types of TPMS:
- Direct TPMS: Uses pressure sensors inside each tire to directly measure air pressure
- Indirect TPMS: Uses wheel speed sensors to detect underinflated tires based on rotational differences
Most modern Toyota Crown models use direct TPMS for more accurate pressure readings.
TPMS Reset and Relearn Procedures for Different Toyota Crown Generations
The process of resetting and relearning TPMS can vary depending on the generation and model year of your Toyota Crown. Let’s break down the procedures for different generations:
14th Generation Toyota Crown (2023-Present)
The latest generation of Toyota Crown features an advanced TPMS that can be reset through the vehicle’s infotainment system.
- Ensure all tires are properly inflated to the recommended pressure
- Turn the ignition to ON
- Navigate to the “Vehicle Settings” menu on the infotainment screen
- Select “TPMS” or “Tire Pressure”
- Choose “Calibrate” or “Reset”
- Follow the on-screen prompts to complete the reset process
The system will automatically relearn the new tire pressures as you drive.
13th Generation Toyota Crown (2018-2022)
For this generation, the reset procedure involves using the TPMS reset button:
- Locate the TPMS reset button (usually under the steering wheel or in the glove box)
- Turn the ignition to ON (engine off)
- Press and hold the TPMS reset button until the TPMS light blinks three times
- Release the button
- Start the engine and wait about 20 minutes for the system to relearn the new tire pressures
During the relearn process, drive the vehicle above 25 mph for at least 10 minutes to ensure proper calibration.
12th Generation Toyota Crown (2012-2017)
The 12th generation Crown uses a similar reset procedure to the 13th generation:
- Ensure all tires are properly inflated
- Turn the ignition to ON
- Locate and press the TPMS reset button until the TPMS light flashes
- Start the engine and drive for about 10 minutes at speeds above 16 mph
This process allows the system to relearn the new tire pressures.
11th Generation Toyota Crown and Earlier (Pre-2012)
For older Crown models, the TPMS reset and relearn process may require a special tool:
- Use a TPMS reset tool to activate each sensor
- Start with the left front tire and work clockwise
- After activating all sensors, the horn should beep to confirm successful relearn
- If no horn beep is heard, repeat the process
Some earlier models may not have TPMS or may use a simpler system that doesn’t require relearning.
Common TPMS Issues in Toyota Crown
While the Toyota Crown’s TPMS is generally reliable, you may encounter some issues:
TPMS Light Stays On
If the TPMS light remains illuminated after resetting:

Inconsistent Pressure Readings
If you notice inconsistent pressure readings:
- Verify tire pressures manually with a gauge
- Check for sensor battery issues (typically last 5-7 years)
- Look for signs of sensor damage or corrosion
TPMS Malfunction
A blinking TPMS light may indicate a system malfunction:
- Check for loose or damaged sensors
- Inspect the TPMS control module for issues
- Consider professional diagnostic services
