Yes. Resetting the tire-pressure monitoring system on a 2020 Honda Accord involves ensuring all tires are inflated to the recommended pressures, then using the car’s TPMS calibration option to relearn the wheel positions. A highway drive afterward helps the system complete the relearn. If the warning light remains after these steps, you may have a slow leak or a faulty sensor that needs inspection.
What you should know before you start
The 2020 Accord uses direct TPMS sensors in each wheel. A reset is typically needed after rotating tires, replacing tires, or if the system loses calibration due to pressure changes. The process relies on correct tire pressures and a guided learning sequence in the vehicle’s settings. If you’re unsure where to find the option, consult the owner’s manual or a Honda service professional.
Reset via the vehicle’s TPMS calibration feature
To reset through the car’s settings, first bring tire pressures to the specification on the driver’s door placard, then initiate the TPMS calibration from the menu and drive to complete the learn process.
- Check and inflate all tires to the recommended cold pressures shown on the driver’s door placard.
- With the ignition on, navigate to the TPMS calibration option in the vehicle’s settings. The path is typically: Settings > Vehicle > TPMS Calibration or TPMS Learn.
- Select Calibrate or Learn to start the TPMS reset.
- Confirm the calibration prompt if one appears.
- Wait for any on-screen confirmation that calibration has begun; the TPMS warning light may blink during the process.
- Drive at a steady highway speed (about 50–60 mph) for 10 minutes or longer to complete the relearn.
Once the relearn is complete, the TPMS light should turn off if the system correctly recognizes all sensors and the tire pressures are within specification.
Why a highway drive helps the relearn
A sustained higher-speed drive provides the TPMS sensors with stable tire-pressure data and allows the vehicle to map each sensor to its corresponding wheel position, finalizing the calibration.
What to do if the light stays on or comes back
If the TPMS warning remains after following the calibration steps and a highway drive, check for:
- Slow leaks in any tire (inspect for punctures or damaged valves).
- Damaged or failing TPMS sensors in one or more wheels.
- Tire rotating, replacement, or pressure changes that weren’t properly captured by the reset.
In such cases, it’s advisable to have the system inspected by a tire shop or Honda dealer, who can perform a diagnostic relearn and verify sensor health.
Alternative approaches and tips
Some owners report success with a straightforward drive and re-check if the TPMS option isn’t readily visible in the menu. If you recently replaced tires or rims, or you notice irregularities after a reset, consider scheduling a diagnostic to confirm the sensors are communicating properly with the ECU.
Summary
Resetting TPMS on a 2020 Honda Accord centers on restoring proper tire pressures and using the car’s calibration feature to relearn sensor positions. Start by inflating all tires to spec, initiate TPMS Calibration in Settings, and then drive on the highway to complete the relearn. If the warning persists after these steps, inspect for slow leaks or faulty sensors and seek professional help as needed.
