Inflate all tires to the recommended cold pressures and reset the TPMS through the car’s system, or drive at highway speeds to re-learn the sensors. The light should turn off once the system recognizes the proper pressures.
Understanding the TPMS on the 2015 Accord
The Tire Pressure Monitoring System (TPMS) in the 2015 Honda Accord uses sensors in each wheel to monitor air pressure. When any tire is underinflated, the dashboard TPMS light—typically a yellow tire icon with an exclamation mark—illuminates. Correcting underinflation is the first step, but you may also need to reinitialize or re-learn the system after adjusting pressures, rotating tires, or replacing sensors. Note that the spare tire is generally not part of TPMS on this model.
Two common reset methods for the 2015 Accord
If your vehicle supports a dedicated TPMS reset option in the settings or via a reset button, use this method first.
- Ensure all tires are cold and inflated to the recommended pressures found on the door jamb placard or in the owner’s manual.
- Turn the ignition to ON with the engine OFF, and locate the TPMS reset button or the TPMS calibration option in the vehicle’s menu (often under Vehicle/Settings or TPMS).
- If using a button, press and hold it until the TPMS indicator on the dash blinks or changes its indication, then release. If using a menu, select Reset/Calibrate and confirm.
- Drive the car at a steady speed (approximately 30–50 mph / 50–80 km/h) for about 10 minutes to complete the calibration.
The exact prompts and wording can vary by trim, so consult the owner’s manual if the interface differs. A successful reset will typically cause the TPMS light to go out after the calibration.
Using the TPMS reset option or calibration via the instrument display is quick and effective if you’ve just corrected pressures or rotated tires. If the light remains after reset, proceed to the auto-calibration method described below or seek service.
If your Accord does not show a reset option in the menu or lacks a dedicated button, you can rely on automatic re-learning by driving with properly inflated tires.
- Inflate all tires to the recommended cold pressures (the same as in the first method).
- Start the car and drive at highway speeds (about 50–60 mph / 80–100 km/h) for at least 10 minutes to allow the sensors to relearn.
- After driving, observe the TPMS light. If it stays on, recheck tire pressures and inspect for leaks or damage, then consider having the sensors inspected if necessary.
- If problems persist beyond a short highway drive, arrange a diagnostic with a dealer or tire shop, as a faulty sensor or TPMS module could be the cause.
Auto-calibration by driving is common when no reset interface is available. It relies on correct tire pressures and road conditions to re-learn sensor positions.
What to do if the light stays on
If the TPMS light remains on after attempting resets and proper pressures, there may be an issue beyond simple re-learn. Consider the following steps:
- Double-check all tires to ensure they’re at the correct cold pressures.
- Inspect tires for punctures, slow leaks, or damaged valve stems.
- Check the spare tire, if applicable, since some systems may trigger issues if pressures are off in nearby tires.
- Have a professional scan the TPMS sensors and module for faults, as a bad sensor or transmitter can cause the light to stay illuminated.
Persistent illumination should be evaluated by a technician, especially if tire damage or sensor failure is suspected. Proper TPMS function is key for tire safety and fuel efficiency.
Summary
The 2015 Honda Accord offers both a manual TPMS reset/calibration route and auto-calibration by driving. Start by correcting all tire pressures, then use the car’s TPMS calibration option if available, or drive at highway speeds to allow the system to relearn. If the light remains on after these steps, inspect tires and consider professional diagnostic service to check sensors and TPMS electronics.
