To reset the TPMS on a 2009 Honda Accord, inflate all tires to the recommended cold pressures and then either use a TPMS reset button if your car has one, or drive at steady highway speeds to allow the system to relearn the new pressures. If the warning light stays on after these steps, have the system inspected for sensor or tire issues.
The Tire Pressure Monitoring System (TPMS) in the 2009 Accord monitors each wheel’s air pressure and alerts you when a tire is underinflated. Depending on the exact trim and options, some cars use a dedicated reset button while others rely on an automatic relearn process once proper pressures are restored and a drive cycle is completed. This article covers both approaches and what to do if the indicator remains illuminated.
Understanding TPMS in the 2009 Accord
TPMS helps prevent driving with underinflated tires, which can affect fuel economy, handling, and tire wear. After you correct tire pressures, the system may relearn automatically or require a manual reset, depending on whether a reset switch is equipped and on the vehicle’s configuration.
Reset methods
Below are the two common paths for resetting TPMS on a 2009 Honda Accord. If your car has a dedicated TPMS reset button, use that method first. If not, rely on the automatic relearn by driving.
With a TPMS reset button (if equipped)
Some 2009 Accords include a TPMS reset button. When present, follow these steps to initiate a relearn.
- Park on a level surface and ensure all tires are inflated to the recommended cold pressures (check the door jamb placard or owner's manual).
- Turn the ignition to ON with the engine OFF.
- Locate the TPMS reset button (often under the dash on the driver’s side or near the knee area). Press and hold the button for about 3–5 seconds until the TPMS indicator light flashes or you hear a confirmation chime.
- Release the button and drive the vehicle at steady speeds, ideally 50–60 mph, for 10–20 minutes so the system can relearn the new pressures.
If the warning light remains after completing these steps, there may be a faulty sensor, a slow-leak tire, or another issue requiring inspection by a professional.
Without a dedicated TPMS reset button (automatic relearn by driving)
If your 2009 Accord does not have a TPMS reset switch, you will typically relearn automatically after correcting tire pressures and driving for a bit. Use this approach when no reset button is present.
- Inflate all tires to the recommended cold pressures listed on the door placard or in the owner's manual.
- Drive on a highway or open road at a steady speed—about 50–65 mph (80–105 km/h)—for roughly 10–20 minutes to allow the system to relearn.
- After the drive, check the instrument cluster. The TPMS warning light should go off if the relearn completed successfully; otherwise, recheck tire pressures and inspect for leaks or sensor issues.
Note: If you recently replaced tires or sensors, or the vehicle’s battery was disconnected, a professional-grade scan tool or dealership service may be required to complete a manual relearn.
Summary
Resetting the TPMS on a 2009 Honda Accord comes down to ensuring correct tire pressures and using either a built-in reset button (if equipped) or a drive-based relearn. The process is straightforward, but persistent warning lights may indicate sensor or tire problems that warrant professional inspection. Regularly checking tire pressures helps the system function reliably and keeps you safe on the road.
