Inflate all tires to the recommended cold pressures and reset the TPMS either via the vehicle’s calibration option or by driving to relearn; if the light remains on after proper inflation, inspect tires and sensors for issues.
What triggers the TPMS light
Understanding why the light appears helps ensure you reset it correctly and avoid false warnings. The TPMS warns when tire pressure drops below a threshold or when a sensor cannot communicate.
Manual TPMS calibration through the vehicle settings
Prerequisites
Before you begin, make sure tires are cold and inflated to the exact pressures on the driver's door jamb placard.
- Turn on the ignition and, if required by your model, start the engine.
- Navigate to the Vehicle Settings menu on the information display or touchscreen.
- Select TPMS Calibration (or TPMS) and choose Calibrate or Reset.
- Confirm the selection and wait for the confirmation message on the display.
- Drive normally, preferably at highway speeds for 10–20 minutes to complete the relearn.
The calibration process should turn off the TPMS light if all tires are at the correct pressures. If the light remains on, try the automatic relearn method below or inspect for tire leaks or damaged sensors.
Automatic relearn by driving
When to use this method
If your Accord lacks a TPMS Calibration option or you prefer a simpler approach, rely on the system’s natural relearn by driving after inflating to spec.
- Ensure all tires are inflated to the recommended cold pressures.
- Start driving on a clear road and maintain steady speeds above 50 mph for about 10–20 minutes.
- Check if the TPMS light goes off once the system finishes relearning. If not, proceed to professional inspection for sensor or valve issues.
Automatic relearn generally resolves once the vehicle has driven long enough at highway speeds and the sensors have communicated with the ECU. If it does not, you may still need a manual calibration or service.
What to do if the light stays on
Persistent TPMS illumination after inflating tires and attempting calibration or relearn can indicate a slow leak, a faulty sensor, or a failed TPMS module. Have the tires inspected by a professional; some sensors may need replacement or reprogramming.
Summary
Resetting the low tire pressure light on a 2017 Honda Accord involves ensuring all tires are inflated to the correct cold pressure and performing a TPMS calibration via the vehicle’s settings, or allowing a normal relearn by driving at highway speeds for 10–20 minutes. If the light remains after these steps, check for leaks or sensor faults and seek professional service.
