P0555 OBD-II: Brake Booster Pressure Sensor Circuit
P0555 Severity
Will P0555 go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P0555?
The Brake Booster uses vacuum to make the brake pedal easier to depress when braking. The Brake Booster Pressure Sensor measures the amount of vacuum inside the brake booster. If the engine computer sees an implausible signal from the Brake Booster Pressure Sensor, code P0555 will be set.
