To reset the tire pressure light on a 2009 Honda Accord, start by inflating all four monitored tires to the recommended cold pressures. Then use the TPMS reset procedure if your model supports it, or drive the car to allow the system to relearn the tire pressures. The exact steps can vary by trim.
This article explains the two common approaches: a manual reset if your Accord has a TPMS/SET switch, and an automatic relearn by driving. It also covers troubleshooting tips if the light stays on.
Does your Accord have a TPMS reset option?
Many 2009 Accords use either a dedicated TPMS reset switch or rely on an automatic relearn that occurs after inflating the tires to spec. If your model includes a TPMS reset button, you can perform a manual reset; if not, you’ll typically rely on letting the system relearn through driving.
Manual reset method (with TPMS/SET switch)
Use this method only if your vehicle has a TPMS reset switch. The steps are designed to trigger the system’s relearn manually.
- Check all four tire pressures and inflate them to the vehicle’s recommended cold pressures, which are listed on the driver’s door jamb sticker or in the owner's manual.
- Turn the ignition to the ON position with the engine OFF.
- Locate the TPMS reset or SET switch. It is commonly found near the left side of the dash, under the steering column, or in the knee area of the driver’s side.
- Press and hold the TPMS/SET button until the TPMS indicator light blinks once or twice, or until you hear a chime or see a confirmation message on the dash.
- Release the button and drive the car at a steady speed above about 30 mph (50 km/h) for around 10 minutes to allow the system to relearn the new pressures.
- Turn the ignition OFF, wait a moment, then start the engine and drive normally to confirm the light stays off.
Note: If your model does not include a reset switch, the manual method may not apply. In that case, proceed with the automatic relearn approach described below.
Automatic relearn by driving
If your Accord doesn’t have a dedicated TPMS reset switch or you prefer a hands-off approach, inflate the tires to the correct pressures and drive on a highway in a steady, straight line for several minutes. The system should automatically relearn as it detects each tire’s pressure and speed during normal driving.
- Ensure all four tires are inflated to the recommended cold pressures.
- Drive at a steady speed on a highway for about 10–15 minutes to allow the system to relearn.
- After driving, check whether the TPMS light has turned off. If it remains on, further action may be needed.
Some Accords will reset the light automatically after a proper tire pressure and relearn cycle; if the light persists, there could be a sensor fault or a slow leak requiring inspection.
Troubleshooting and caveats
Common reasons the tire light stays on include underinflation, a puncture, a faulty TPMS sensor, or a damaged wheel valve. If you recently added sealant or used a temporary fix after a puncture, these can affect sensor readings. Always start with a cold tire check and avoid driving with significantly underinflated tires.
Summary
Resetting the tire pressure light on a 2009 Honda Accord usually involves inflating all monitored tires to the recommended cold pressures and then either performing a manual reset (if your model has a TPMS/SET switch) or allowing the system to relearn automatically by driving. If the light remains after these steps, have the system checked by a qualified technician to identify sensor faults or leaks.
