Solution

1. Preparation

Gather necessary tools and parts.
Ensure you have a reliable OBD-II scanner, tire pressure gauge, and a reset tool if needed.
Park the vehicle on a flat surface and turn off the ignition.

2. Inspect and Replace TPMS Sensors

Sub-step 1: Remove the tire from the wheel. Use a jack to lift the vehicle and secure it with jack stands.
Sub-step 2: Use a tire iron to remove the wheel lug nuts and take off the tire.
Sub-step 3: Locate the TPMS sensor mounted on the valve stem. Inspect it for any visible damage or corrosion.
Sub-step 4: If the sensor is damaged, replace it with a new TPMS sensor compatible with the Honda Accord (make sure to check the part number).
Sub-step 5: Reinstall the tire onto the wheel, hand-tighten the lug nuts, and then torque them to the manufacturer's specifications (usually around 80 ft-lbs).

3. Reset the TPMS

Sub-step 1: Turn the ignition to the “ON” position without starting the engine.
Sub-step 2: Locate the TPMS reset button (usually beneath the steering wheel) and press it until the TPMS light blinks three times and then turns off.
Sub-step 3: Drive the vehicle for a few minutes to allow the system to recalibrate.
