How does Honda monitor tire pressure?

How Honda Monitors Tire Pressure
Honda monitors tire pressure using a Tire Pressure Monitoring System (TPMS). There are two types of TPMS used in Honda vehicles: direct and indirect.
Direct TPMS: This system uses sensors attached to the valve for the most accurate reading of tire pressure. When the tire pressure is low, the system alerts the driver by illuminating the TPMS indicator within the gauge cluster.
Indirect TPMS: For vehicles equipped with indirect TPMS, the system uses the anti-lock brake system to determine approximate tire pressure. This system does not have air pressure sensors inside the tires. Instead, it detects a low tire by comparing relative wheel speeds via the anti-lock brake system (ABS) wheel speed sensors. When a tire loses air, its diameter decreases slightly, and the system detects this change to alert the driver.
Resetting the TPMS Warning Light
If the TPMS warning light comes on, it can be reset by following specific steps, which may vary depending on the model and technology of the Honda vehicle.
For newer Honda models, the TPMS needs to be recalibrated after reinflating tires, changing a tire, or getting them rotated. This recalibration process involves driving the vehicle for about 30 minutes at speeds between 30-65 miles per hour. After this, the TPMS will automatically stop recalibrating, and the tire pressure monitoring system will be reset.
For older models, the reset process may involve pressing and holding a TPMS reset button until the warning light blinks twice.
Conclusion
Honda uses both direct and indirect TPMS to monitor tire pressure in its vehicles. The system alerts the driver when tire pressure is low and provides instructions for resetting the TPMS warning light based on the specific model and technology of the vehicle.

How does my car monitor tire pressure?

Direct TPMS uses a sensor mounted in the wheel to measure air pressure in each tire. When air pressure drops 25% below the manufacturer’s recommended level, the sensor transmits that information to your car’s computer system and triggers your dashboard indicator light.

How does Honda TPMS calibration work?

Any time you inflate, change, or rotate one or more of the tires, you need to recalibrate the system. The calibration process requires approximately 30 minutes of cumulative driving at speeds between 30–65 mph (48–105 km/h). The vehicle must be stopped to begin calibration, and the process finishes automatically.

When did Honda start using indirect TPMS?

Type of TPMS system:
Indirect TPMS system for years 2014-2020.

Does Honda TPMS reset automatically?

After you’ve had the chance to fill up your tires to the proper level, here’s how to reset the tire pressure light in your Honda CR-V below in a few simple steps: Drive at or above 50 mph to reset the sensor for 10 minutes. This can cause your sensor to reset the next time you turn on the car.

How does tire pressure sensor communicate with car?

The sensor transmits that information via low-frequency radio to the vehicle’s onboard computer and, if the car has one, to a corresponding display in the instrument cluster. It reads out in pounds per square inch (psi), and it illuminates an amber warning light to alert you if one or more tires are low on air.

What type of TPMS does Honda use?

Indirect Systems
Honda indirect TPMS systems do not have air pressure sensors inside the tires. Rather, they detect a low tire by comparing relative wheel speeds via the anti-lock brake system (ABS) wheel speed sensors. When a tire loses air, its diameter decreases slightly.

How do tire pressure sensors send data?

They typically use wireless technology, such as RF signals, to transmit the collected data. When a tire’s pressure drops below the recommended threshold, the TPMS sensors transmit a signal to the vehicle’s computer, which then triggers a low tire pressure warning.

Why is my TPMS light on but tires are fine?

The causes can be a malfunction, or the weather changes. Other reasons why your TPMS light may still be blinking is because your tire may be damaged, or you might have gotten a recent tire replacement. Overall, the reasons can be vast, which is why it is best to take your car to a technician for professional diagnosis.

How long does Honda TPMS calibration take?

Any time you reinflate your tires, change a tire, or get them rotated, the TPMS needs to be recalibrated before it’ll work properly again. Once you start the recalibration process, it takes about 30 minutes of driving between 30-65 miles per hour.

What is the problem with the TPMS sensor on a Honda?

If your Honda TPMS light is on and flashing, it could mean that the sensor battery is failing or that the tire pressure sensors are malfunctioning. Whatever the issue is, you should bring your vehicle into our Service Center as soon as possible. Our expert technicians can quickly diagnose and correct the problem.
