What is the TPMS sensor on a Honda Accord?

The TPMS sensor in a Honda Accord is the tire pressure monitoring system component that measures air pressure in each tire and relays that data to the car’s computer via a radio signal, helping you monitor tire pressure and avoid under- or over-inflation.

How the TPMS works in the Honda Accord

In modern Accords, each wheel uses a direct TPMS sensor that sits on or inside the wheel via the valve stem. The sensor measures air pressure and temperature, runs on a small battery, and sends a radio signal to the TPMS control module. The instrument cluster displays individual tire pressures and triggers a warning if a tire drops below the recommended level.

Below are the main components involved in Honda Accord TPMS.

• Wheel-mounted sensor (transmitter) that monitors tire pressure (and temperature) and communicates wirelessly


• TPMS control module inside the vehicle that interprets sensor data


• Receiver/antenna network that captures sensor signals


• Instrument cluster or display screen that shows tire pressures or a warning


• Relearn/calibration procedures used after sensor replacement or tire rotation

These parts work together to provide real-time pressure readings and to alert drivers to underinflated tires, improving safety and fuel efficiency.

Direct TPMS vs indirect TPMS in the Honda Accord

Direct TPMS

Direct TPMS uses a dedicated sensor in each wheel to measure the actual tire pressure. The sensor sends data to the car’s TPMS control module by radio. Benefits include precise, real-time readings for each tire and alerts when any tire is underinflated. The sensors are battery-powered and eventually require replacement when their batteries die, usually after 5–10 years. Replacing a sensor or the entire wheel sensor assembly can be necessary after severe impact or wear.

Indirect TPMS

Indirect TPMS does not use wheel-mounted pressure sensors. Instead, it estimates tire pressure by comparing the rotation speed and diameter of each wheel using ABS/ESP data, then infers low pressure when a tire’s rolling circumference changes. It’s less precise and can be slower to detect, especially if a tire is only slightly underinflated or has a different size. Honda generally ships newer Accords with direct TPMS, but older trims or certain markets may rely on indirect monitoring if direct is unavailable.

What to do if the TPMS light is on

If the warning light comes on, start with basic checks and a known-good baseline for tire pressure. The following steps help determine whether the issue is a simple pressure problem or a sensor fault.

• Check all tire pressures with a reliable gauge and inflate to the vehicle’s recommended specification (usually on the door jamb placard or owner's manual).


• Inspect tires for damage, punctures, or slow leaks and inspect valve stems for leaks or damage.


• If pressures are correct and the light remains, a sensor issue or TPMS module fault may be present; professional service may be required.


• Perform the TPMS relearn/calibration procedure after installing new sensors or rotating tires (procedure varies by model year; consult the owner's manual or a Honda dealer).


• Drive the car as advised by the manual (often driving at 30–50 mph for several minutes) or use the vehicle’s TPMS relearn option in the settings to complete the learn cycle.

Inconsistent readings or a persistent warning typically requires diagnostic testing with a scan tool to verify sensor IDs and battery health.

Maintenance and replacement considerations

Maintenance and replacement decisions can affect safety and cost. Here are key points to consider for the Honda Accord TPMS.

• Sensor lifespan: Direct TPMS sensors typically last 5–10 years; batteries are not replaceable separately in most designs, so the whole sensor is replaced when the battery dies.


• Replacement costs: A single wheel sensor can cost roughly $60–120 (parts) plus labor; total replacement for all four wheels is common when replacing all sensors at once, often during tire service.


• Relearn after service: After installing new sensors or rotating tires, a relearn/calibration is usually required so the system recognizes the correct sensor IDs.


• Professional service: If the TPMS light stays on after inflating to spec and performing a relearn, a diagnostic with a scan tool may be necessary to identify a faulty sensor, transmitter, or module.

Regular tire maintenance and sensor care help avoid unexpected warnings and ensure accurate readings when you need them most.

Summary

The TPMS sensor on a Honda Accord is a tire-pressure-sensing device mounted in each wheel, part of a direct or indirect system that alerts you to underinflated tires. In modern Accords, direct TPMS with four wheel sensors provides precise, real-time readings, but sensors wear out and may require replacement or recalibration. Regularly check tire pressures, be aware of relearn procedures after tire service, and consult a dealer or qualified tire service shop if the warning persists.

Can I replace a TPMS sensor myself?

Yes, you can replace a TPMS sensor yourself, but it requires specialized tools and knowledge, and the process can be more difficult than it appears, especially without a tire machine to break the bead of the tire. The process involves removing the wheel, deflating the tire, breaking the tire bead to access the sensor, replacing the sensor, and then re-inflating and re-training the new sensors. 
Steps for replacing a TPMS sensor

1. Safety first: Park on a flat surface, engage the parking brake, and wear safety glasses and gloves. 
2. Remove the wheel: Use a lug wrench to loosen the lug nuts, then use a jack and jack stands to lift the vehicle and remove the wheel. 
3. Deflate the tire: Use a valve core removal tool to let all the air out of the tire. 
4. Break the tire bead: This is the most difficult part without special equipment. You can use a tire machine or manually break the bead by using leverage with tools like a 2x6 piece of wood to push the tire away from the rim. 
5. Remove the old sensor: Once the tire bead is broken, you can access the sensor behind the valve stem and unscrew the nut that holds it in place. Some sensors have a thicker rubber stem that is pushed through the hole and may require a special tool to remove. 
6. Install the new sensor: Screw the new sensor into place, making sure to tighten it properly to avoid damage. 
7. Re-mount the tire: With the new sensor in place, it's time to put the tire back on the rim. This is often done by hand or with a tire machine. 
8. Inflate the tire: Fill the tire to the correct pressure as listed on the driver's side door jamb. 
9. Re-train the sensors: The new sensor needs to be programmed or "re-trained" to the vehicle's computer. This process varies depending on the make and model of the vehicle and often requires a special TPMS tool to get the system to recognize the new sensors. 
10. Re-install the wheel: Put the wheel back on the vehicle, lower it, and tighten the lug nuts. 
11. Check tire balance: Some DIYers claim you can skip re-balancing if you put the tire back in the same position, but others recommend re-balancing the tire for safety and a smoother ride. 

Considerations before replacing a TPMS sensor yourself

• Tools needed: You will need a TPMS programming tool and a valve core removal tool, as well as a jack, lug wrench, and tire iron. 
• Difficulty: Breaking the tire bead manually can be challenging, especially with certain types of tires, such as all-season tires. 
• Cost: While you can save money on labor by doing it yourself, you still need to purchase the replacement sensors. 
• Vehicle compatibility: Ensure you purchase the correct sensor for your vehicle, as some universal sensors may not be compatible with all makes and models and could cause false alerts. 
• Tire balancing: If the wheel is not re-balanced after replacing the sensor, the tire may not be balanced properly, which can lead to vibrations at higher speeds and a shorter tire lifespan. 
• Safety: Always prioritize safety. Work in a well-lit area and use caution when using a jack and other tools. 

Can I still drive if my TPMS sensor is bad?

You can drive with a bad tire pressure sensor, but it is not recommended because the system won't be able to alert you to a dangerous low-pressure situation. You should have the sensor replaced as soon as possible to avoid potential safety issues like tire failure, reduced fuel economy, and uneven tire wear. While you're waiting for a repair, manually check your tire pressure with a gauge to ensure they are properly inflated.
 
Risks of driving with a bad TPMS sensor

• Compromised safety: The primary risk is not being alerted to a flat tire, which can lead to a blowout and serious accidents. 
• Tire damage: Driving on a flat tire can cause significant damage to the wheel, brakes, and other components. 
• Reduced fuel efficiency: Underinflated tires increase rolling resistance, which can decrease your gas mileage. 
• Uneven tire wear: Poor tire pressure can cause your tires to wear out unevenly and prematurely. 

What to do

1. Manually check your tires: Use a tire pressure gauge to check the pressure in all four tires immediately and inflate them to the manufacturer's recommended level. 
2. Schedule a replacement: Book an appointment with a qualified technician to diagnose the faulty sensor and replace it. 
3. Consider replacing all sensors: If one sensor has failed (often due to a dead battery), the others may be close to failing as well. Replacing them all at once can save you future visits and costs.

What does TPMS light mean on a Honda Accord?

Tire Pressure Monitoring System
TPMS stands for Tire Pressure Monitoring System.
Put simply, it uses tire pressure sensors to track your vehicle's air pressure. If the monitoring system detects that one (or more) of your Honda's tires is not at the recommended pressure, the TPMS light will go off.
