The TPMS light can be reset by ensuring all tires are inflated to the manufacturer’s recommended pressures and then recalibrating the system either through the in-dash TPMS calibration menu or by performing a highway relearn. This process helps the system relearn tire positions after rotations or repairs and can turn off the warning if there are no tire-pressure issues.
In practice, you’ll start by checking tire pressures and then choose one of two methods: (A) use the vehicle’s TPMS Calibration feature in the settings, or (B) perform a highway relearn if the option isn’t available or you prefer a manual approach. If a tire is actually underinflated, leaking, or a sensor is faulty, the light may stay on even after a reset, and you should address the underlying issue.
Prepare the tires and the system
Why proper tire pressure matters
Correct tire pressures are essential before resetting TPMS because the system learns from accurately inflated tires. A persistent low tire can cause the warning to return after reset.
Before attempting a reset, make sure all four tires (and the spare, if applicable) are inflated to the recommended pressures listed on the door placard when the tires are cold.
Follow these steps to prepare the vehicle for TPMS reset:
- Check and adjust all tire pressures to the specification printed on the driver's door placard (cold tire pressure).
- Inspect tires for cuts, punctures, or excessive wear that could cause leaks or sensor damage.
- If you recently rotated or replaced tires, note that a recalibration may be required to ensure accurate readings.
Completing these checks helps ensure the TPMS reset process succeeds and the warning light stays off after calibration.
Reset TPMS via the vehicle’s calibration menu
In-dash calibration method
Many 2018 Honda Accord trims let you recalibrate the TPMS from the in-dash menu. This is the preferred method if your model includes the option directly in Settings.
To calibrate using the on-board menu, follow these steps:
- Turn the ignition to ON with the engine OFF and park the car.
- On the multi-information display, navigate to Settings → Vehicle → TPMS Calibration → Calibrate (or a similar option).
- Confirm Calibrate and wait for the system to acknowledge that calibration is complete.
- Drive normally and then on a highway at about 50–60 mph (80–97 km/h) for 10–15 minutes to finalize the relearn.
If you don’t see a TPMS Calibration option, proceed to the highway relearn method or consult the owner’s manual for your exact trim, as paths can vary by model.

Notes on highway relearn
If your Accord trim doesn’t show a dedicated TPMS Calibration setting, you can often trigger a relearn by driving at highway speeds after ensuring proper tire pressures. This method relies on the system learning the four sensor positions during a sustained drive.
Follow these steps for a highway relearn:
- Ensure all four tires are inflated to the recommended cold pressures.
- With the ignition ON, drive at a steady speed of 50–60 mph (80–97 km/h) for 10–15 minutes to allow sensors to relearn.
- If the warning light remains after the highway drive, repeat the drive once more or re-check tire pressures for any slow leaks.
- If the TPMS light persists after multiple attempts, have a tire technician check for sensor faults or leaks, as a faulty sensor can prevent a successful reset.
Note that this method may take longer to finalize, and repeated attempts may be required if a tire pressure issue is found or if a sensor is faulty.
Summary
Resetting the TPMS light on a 2018 Honda Accord centers on proper tire pressures and either using the built-in TPMS Calibration option in Settings or performing a highway relearn. Always start by inflating tires to the door placard specification and inspecting for leaks or damage. If your trim supports it, the calibration menu provides a direct reset path; if not, a highway relearn is usually effective. Should the light not go out after these steps, professional inspection is advised to rule out sensor faults or slow leaks.
