To reset the TPMS on a 2018 Honda Accord, inflate all four tires to the recommended cold pressures, use the TPMS reset control if your car has one, and drive at highway speeds to allow the sensors to relearn. If your model lacks a reset button, the system will typically relearn automatically after driving with proper tire pressures.
What you need
Before attempting a reset, gather the basics and know where to find the reset control. You’ll also want to confirm the tires are at the correct cold pressures using the door placard as a reference.
- Access to a tire pressure gauge to verify cold tire pressures
- The recommended cold tire pressures for your Accord (found on the driver’s door jamb placard)
- The TPMS reset control or button (if your trim level includes it) located on or near the left side of the dash
- A safe driving environment to complete the relearn drive (preferably highways or open roads)
With everything ready and the tires inflated to spec, you’re prepared to perform the relearn procedure and verify the system is reset.
Step-by-step reset procedure
Use the following steps to reset the TPMS, if your 2018 Accord has a dedicated TPMS reset control. If your car doesn’t have a reset button, the system will generally relearn automatically once the tires are properly inflated and you drive for a period of time.
- Ensure all four tires are inflated to the manufacturer’s recommended cold pressures
- Turn the ignition to ON with the engine off
- Locate the TPMS reset button on the left side of the steering column area (often labeled “TPMS” or with a tire icon); press and hold it until the TPMS indicator in the instrument cluster blinks slowly three times, then release
- Start the engine
- Drive at speeds of about 50 mph (80 km/h) or higher for roughly 10 minutes to allow the sensors to relearn
After driving, the TPMS warning light should either go out or stop flashing. If the light remains on, recheck all tire pressures and consider a reset attempt again. Some vehicles may require repeating the steps or may indicate a sensor issue.
Alternative relearn method and troubleshooting
Not all 2018 Accord trims include a TPMS reset button. If yours doesn’t, or if the light stays on after following the steps above, rely on the automatic relearn that occurs after normal driving with properly inflated tires. If issues persist, you may have a faulty sensor, a damaged tire, or a sensor battery nearing end of life. In such cases, a visit to a Honda dealer or tire shop can diagnose and replace the sensor if needed.
Tips and common issues
- Always start with cold tires when checking or adjusting pressures; driving heats tires and changes readings
- Never rely on a single tire’s pressure; check all four for uniform readings
- Sensor replacement is typically needed when a TPMS light stays on despite correct pressures
- Battery life for TPMS sensors is limited and varies by vehicle, usually several years; sensors may need replacement rather than repair
Understanding these factors helps ensure the TPMS remains accurate and reliable after a reset or tire service.
Summary
The standard path to resetting the TPMS on a 2018 Honda Accord involves inflating all tires to the recommended cold pressures, using the TPMS reset control if equipped, and driving at highway speeds for about 10 minutes to relearn. If your model lacks a reset button, auto relearn through normal driving with proper pressures is usually sufficient. If the warning light persists, verify tire pressures again and consider professional inspection of sensors or tires.
