This procedure relearns the Tire Pressure Monitoring System (TPMS) sensors on a 2018-2024 Honda Accord after tire rotation, replacement, or pressure adjustment using the vehicle's built-in relearn procedure.

Warnings

Tools required

Preparation

1. Ensure all four tires are inflated to the correct pressure as specified on the driver's door jamb placard (typically 32-35 PSI cold)
2. Verify the vehicle is parked on level ground with the ignition off
3. Ensure the vehicle has been stationary for at least 2 minutes before beginning the relearn procedure

Procedure

1. 1

   Verify tire pressures
   Using a tire pressure gauge, check all four tires and inflate or deflate to match the pressure specification on the driver's door jamb sticker. Ensure pressures are checked when tires are cold (vehicle has not been driven for at least 3 hours).
2. 2

   Turn ignition to ON position
   Insert the key and turn the ignition to the ON (II) position without starting the engine. For push-button start models, press the START button twice without pressing the brake pedal. Verify the instrument cluster illuminates.
3. 3

   Access the TPMS calibration menu
   On the instrument cluster, use the steering wheel controls to navigate through the menu. Press the i (information) button repeatedly until you reach the Vehicle Settings or Customize Settings menu. Navigate to TPMS Calibration using the up/down arrow buttons.
4. 4

   Initiate TPMS calibration
   Select 'Calibrate' or 'Initialize' when the TPMS Calibration screen is displayed. The system will prompt you to confirm. Press and hold the SEL/RESET button or select 'Yes' to confirm calibration. The TPMS indicator light on the instrument cluster will blink twice to confirm the relearn process has started.
5. 5

   Start the engine and drive
   Start the engine and drive the vehicle at speeds between 30-65 mph for 20-30 minutes. The system will automatically complete the relearn process during normal driving. Ensure you drive on relatively straight roads with minimal stops to allow the system to properly calibrate.
6. 6

   Verify TPMS light status
   After completing the drive cycle, turn off the ignition and restart the vehicle. Check that the TPMS warning light is no longer illuminated on the instrument cluster. If the light remains on or is blinking, repeat the calibration procedure from Step 2.

Verification

• Confirm the TPMS warning light is off after restarting the vehicle
• Verify all tire pressures are still at the correct specification
• Drive the vehicle for a few minutes and confirm the TPMS light does not illuminate
• Check the instrument cluster display to ensure individual tire pressures are being reported correctly (if equipped with individual tire pressure display)
