DTC P0555: Brake Booster Pressure Sensor Circuit: Action
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
This DTC sets if the information in the brake booster vacuum sensor message is outside of the programmed set of parameters. This is most likely due to vacuum sensor concerns, wiring harness concerns or vehicle communication concerns. RETRIEVE and DIAGNOSE all ABS module DTCs. Go to the ABS Module DTC Chart.
