When a vehicle displays a Honda code P0555, it indicates that the brake booster pressure sensor A circuit has detected a high voltage. This code is typically caused by poor connections or loose terminals at the brake booster pressure sensor A and the PCM, an “open” circuit between the PCM and brake booster pressure sensor A, and a faulty brake booster pressure sensor A. The PCM may need to be updated with the latest software or may have a defective PCM. Fortunately, there are solutions to these problems that can help prevent further damage to the Honda vehicle.
