Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Ford Bronco · 2021–2024
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 (23V155) for certain 2022 Bronco Raptor and 2023 Bronco Wildtrak vehicles because a cracked steering gear ball nut retainer could cause increased steering effort or prevent the steering wheel from turning. 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.

Ford Mustang · 2011–2014
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. No NHTSA safety recall covers steering on 2011-2014 Mustangs, so repairs are typically out of pocket once warranty has expired. Owners describe steering becoming very heavy at low speeds or during parking maneuvers, creating a clear safety concern.
Common Symptoms
- Sudden loss of power steering assist
- Steering becomes very heavy
- Wrench light illuminated
- Service AdvanceTrac message
- Intermittent steering assist after restart
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.

What does C200B mean?
C200B stands for "Steering Shaft Torque Sensor 1 Fault." 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.
What are the most common causes of C200B?
The most common causes of C200B are: Faulty steering shaft torque sensor, Damaged wiring or connectors to the sensor, Corroded or loose connector pins, Internal fault in the steering gear/EPAS assembly, Power steering control module fault, Low system voltage / charging issue. The specific cause varies by vehicle.
How much does it cost to fix C200B?
