C200B on Ford by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Power steering assist fault message
- Very heavy steering effort
- Intermittent steering assist loss
- Steering wheel jerks or binds
- Warning lights on dash
How to Fix
Scan the PSCM/ABS modules for steering-related faults and inspect for active recalls or field service actions before replacing parts. Dealers typically replace the steering gear/rack assembly and perform module calibration; in intermittent cases, wiring and connector checks at the rack and battery voltage verification are also important. If recall coverage applies, the repair should be completed through Ford rather than paid out of pocket.

How to Fix
Scan the PSCM for steering-related DTCs and verify whether the VIN is covered by recall or field service action. Repairs may include software updates, torque sensor/steering gear replacement, or replacement of the electric power steering assembly depending on the fault. Battery and charging system health should also be checked because low voltage can aggravate EPS faults.

C200B is a chassis (C) code, used notably by Ford, indicating the power steering control module detected a fault with steering shaft torque sensor 1. This sensor measures how much turning force the driver applies and is essential for the electric power-assisted steering system to provide the correct amount of assist. When it fails, the system may reduce or lose power steering assist, making the wheel hard to turn. Because this affects steering effort, it should be addressed promptly. On Ford it is documented across 2 models: Bronco, Mustang.
