The tire pressure light on a 2018 Honda Accord can be reset after you’ve brought all tires up to the recommended cold pressures and performed a TPMS relearn. Depending on your trim, you will either use a dedicated TPMS reset button or the vehicle’s settings menu to recalibrate, or you can rely on a highway-speed drive to complete the relearn. If the light remains after these steps, further inspection may be necessary.
What the TPMS does and when it needs resetting
The Tire Pressure Monitoring System (TPMS) warns when one or more tires are underinflated or when sensors have been recalibrated after a tire change. A proper reset ensures the system correctly tracks tire pressures and avoids false warnings. Always start by ensuring all tires (including the spare, if applicable) are inflated to the manufacturer’s specifications printed on the driver’s door jamb placard or in the owner’s manual.
Two common reset methods for the 2018 Accord
These are the two typical paths to reset the TPMS on a 2018 Accord. The exact method depends on the trim level and whether your model includes a physical TPMS button or uses the i-MID/Instrument Cluster settings.
TPMS reset button method (if your model is equipped)
If your Accord has a TPMS reset button, follow these steps to initiate a relearn check and calibration.
- Ensure all tires are cold and inflated to the recommended pressures listed on the driver’s door jamb placard.
- Turn the ignition to ON with the engine OFF.
- Locate and press (and hold, if required) the TPMS reset button until you see a confirmation on the dash or the TPMS light behavior changes (often a blink or soft flash).
- Release the button and drive at speeds above 30 mph (50 km/h) for about 10 minutes to complete the relearn.
- Confirm that the TPMS warning light stays off after the relearn is complete and you’ve driven for a while.
Note: If you cannot locate a TPMS button or the light does not reset, proceed with the Settings menu method below or consult the owner’s manual for your exact trim.
Settings menu / i‑MID calibration method (through the display)
Many 2018 Accord models allow a TPMS calibration via the vehicle’s settings. Use this method if there’s no dedicated reset button or if you prefer the screen-based approach.
- Make sure all tires are inflated to the recommended pressures.
- Turn the ignition to ON (engine off) or start the engine as your manual instructs for the relearn flow.
- On the steering wheel, navigate to Settings > Vehicle > Tire Pressure Monitoring (or TPMS) > Calibrate/Relearn and select Confirm or OK.
- Drive at highway speeds (typically 30–50 mph) for 10–15 minutes to complete the relearn.
- Check that the warning light has cleared after the relearn is finished.
If your vehicle doesn’t show a TPMS calibration option in the menu, or the light remains on after performing a relearn, a sensor issue or a tire leak may be involved. In that case, a dealership or tire shop can diagnose with a TPMS tool and service or replace sensors as needed.
Troubleshooting if the light stays on
Persistent TPMS warnings after inflating tires and attempting a relearn can indicate one of several issues. A slow leak from a puncture or damaged valve stem is common, as are faulty TPMS sensors or dead batteries in sensor units. In such cases, have the tires inspected, and consider a diagnostic scan for the TPMS system. Replacing a sensor typically requires professional service.
What to do next if you’re without a reset option
If you cannot locate a reset button and the Settings menu method isn’t available on your model, the light may still reset after normal driving once tires are properly inflated. If the light reappears, or if you notice a tire with persistent low pressure, contact a tire professional or Honda service for a formal TPMS check. Regular maintenance and prompt attention to leaks will help ensure the TPMS is accurate and reliable.
Summary
To reset the 2018 Honda Accord tire pressure light, start by inflating all four tires to the recommended cold pressures on the door jamb placard, then perform a TPMS relearn using either a dedicated reset button (if equipped) or the settings menu/i-MID calibration. Drive at a steady highway speed for about 10–15 minutes to finalize the relearn. If the light stays on after these steps, or you suspect a sensor issue, consult a professional to diagnose and service the TPMS system.
