The tire pressure warning light on a 2015 Honda Accord cannot be permanently turned off with a switch. It will go out after all tires are inflated to the correct cold pressures and the TPMS is reset or relearned. If it stays on, there may be a slow leak or sensor fault that needs attention.
Understanding the TPMS light on your Accord
The tire pressure monitoring system (TPMS) alerts you when one or more tires are underinflated or if there is a sensor issue. Because underinflated tires can affect handling and safety, the light is designed to stay active until the issue is resolved. In most cases, the remedy is to inflate to the recommended level and reset the system so it can relearn the new tire pressures.
What you’ll need before resetting
To properly reset the TPMS, you should first ensure all four main tires are inflated to the vehicle’s recommended cold pressures. Then you’ll perform a reset or relearn procedure. Keep in mind that the spare tire is not typically part of TPMS.
Before attempting a reset, gather these basics:
- A reliable tire gauge to verify each tire’s pressure
- Your vehicle’s door jamb sticker or owner’s manual to confirm the recommended cold tire pressure
- Access to the TPMS reset procedure for your model, or the ability to drive at highway speeds for a relearn if your car doesn’t have a reset button
- Patience to confirm the light goes out after the procedure
Inflating tires to the correct pressure and performing the reset are the two core steps you’ll follow. If any tire wears unevenly, shows a nails, or has a slow leak, address that issue first.
Steps to inflate and reset the TPMS (two-part process)
Follow these steps in sequence to address a TPMS warning on a 2015 Accord. The exact method can vary by trim and market, but the general approach is consistent: inflate to spec, then reset or relearn the system.
- Check the tire pressures with a gauge. Find the recommended cold pressure on the driver’s door jamb sticker and inflate each tire to that specification when the tires are cold (before driving). If you’re unsure, start with the sticker value and adjust as needed.
- Inspect tires for obvious issues. Look for punctures, cuts, bulges, or slow leaks. If you find a problem, repair or replace the tire before proceeding.
- Inflate all four tires (and only the four main tires—spare is typically not monitored) to the recommended cold pressure. Recheck after inflation to ensure accuracy.
- Reset the TPMS if your model has a dedicated reset button: locate the TPMS reset button (often under the dash to the left of the steering column or in the glove box). With the ignition ON and the engine off, press and hold the button until the TPMS indicator on the dashboard confirms (a flashing light or a message). Release, then drive at 40–50 mph (65–80 km/h) for about 10 minutes to complete the relearn.
- If there is no reset button, perform a relearn by driving: with properly inflated tires, drive on a highway at a steady speed (typically above 50 mph / 80 km/h) for about 10 minutes to allow the system to relearn the new pressures.
After performing the reset or relearn, monitor the dashboard. If the light remains on, the system may have a faulty sensor or a more persistent leak that requires professional diagnostics.
What to do if the light stays on after reset
Persistent TPMS illumination can indicate a faulty sensor, a damaged wheel, or a leak that’s not easily visible. In this case, schedule a diagnostic check with a Honda dealer or a qualified tire shop. They can read TPMS codes, test sensors, and replace a malfunctioning sensor if needed.
Note: Do not ignore the TPMS warning. Driving with underinflated tires can reduce fuel efficiency, increase tire wear, and compromise handling and braking.
Summary
In short, there isn’t a permanent off switch for the TPMS on a 2015 Honda Accord. Properly inflate all four tires to the specification shown on the door jamb sticker, then use the TPMS reset or relearn procedure suitable for your model. If the warning persists after inflation and reset, you likely have a sensor issue or a slow leak that should be inspected by a professional.
Additional notes
For precise instructions tailored to your exact trim and market, consult the owner's manual or contact a Honda service center. The exact location of the TPMS reset button and the relearn procedure can vary by model year and region, so referring to official documentation helps ensure you follow the correct steps.
