C1B00 on Ford
Steering Angle Sensor Fault
C1B00 on Ford vehicles indicates steering angle sensor fault. Au7o has documented this code across 3 Ford models — most commonly on Bronco, Mustang, Transit. 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. Typical repair costs on Ford range from $250 to $3,500, depending on the specific model and root cause.
Common Causes of C1B00
- •Faulty steering angle sensor / clockspring assembly
- •Calibration not performed after alignment, battery, or steering service
- •Damaged or corroded sensor wiring/connector
- •Erratic or implausible sensor signal vs. other inputs
- •Power steering control module fault
- •Low system voltage or poor ground
- •Worn or damaged steering column components
C1B00 on Ford by Model
Ford Bronco(1 issue)
- Electric Power Steering Assist Loss and Steering Rack Failure2021-2024
Multiple Bronco owners reported sudden loss of power steering assist, often accompanied by warning messages and very heavy manual steering effort at low speeds. The issue has been tied to failures in the electric power steering system and steering gear/rack assembly, and Ford issued a safety recall for certain vehicles because an internal steering gear component could fail and cause loss of steering control. Owner complaints and forum reports describe intermittent assist loss first, then complete failure requiring rack replacement.
Ford Mustang(1 issue)
- 2011-2014 3.7L V6 Electric Power Steering Assist Failure2011-2014
2011-2014 Mustangs equipped with electric power steering can experience sudden loss of steering assist, often accompanied by a wrench light and a 'Service AdvanceTrac' or steering assist warning. Ford issued recalls and service actions on certain vehicles for steering gear or power steering control module concerns. Owners describe steering becoming very heavy at low speeds or during parking maneuvers, creating a clear safety concern.
Ford Transit(1 issue)
- Electric Power Steering (EPAS) Assist Loss / Steering Fault Warnings2015-2020
NHTSA complaints include intermittent or sudden loss of power steering assist with warning messages, making the van difficult to steer at low speeds. Reports often describe the issue occurring after a restart, during parking maneuvers, or intermittently with electrical/communication faults. The Transit’s EPAS system can set steering-related DTCs and may require module diagnosis or replacement depending on root cause.
