C1B00: Steering Angle Sensor Fault
4 vehicles · 2 makes · $250-$3,500 repair
Most Reported On
C1B00 is an OBD-II diagnostic trouble code meaning “Steering Angle Sensor Fault.” C1B00 is a manufacturer-specific chassis code (commonly Ford) indicating the power steering or stability control module detected a fault with the steering angle (steering wheel position) sensor. This sensor tells stability control and electric power steering where the steering wheel is pointed, which is essential for traction/stability control and assist calibration. When the signal is missing, erratic, or fails plausibility checks, the module sets this code and may disable stability control and reduce or alter power steering assist. Steering still works mechanically, but related driver-assist systems may be limited. This code is most commonly reported on 2015-2020 Ford Transit, 2021-2024 Ford Bronco, and 2011-2014 Ford Mustang, plus 1 other vehicle, with repair costs ranging from $250 to $3,500.
