C0051 on Ford
LF Wheel Speed Sensor Circuit Range/Performance
C0051 on Ford vehicles indicates lf wheel speed sensor circuit range/performance. Au7o has documented this code across 2 Ford models — most commonly on Escape, Fusion. C0051 is a chassis/brake code meaning the ABS module is reading an unreliable or out-of-range signal from the Left Front (LF) wheel speed sensor. The sensor counts how fast that wheel turns by sensing teeth on a tone ring, and the computer expects its signal to track logically with the other three wheels. When the LF reading is erratic, intermittent, or doesn't match vehicle speed, the module sets this 'range/performance' code. It generally means the data is present but doesn't make sense, which can disable ABS, traction control, and stability control until corrected. Typical repair costs on Ford range from $100 to $3,500, depending on the specific model and root cause.
Common Causes of C0051
- •Metal debris, rust, or brake dust contaminating the LF sensor or tone ring
- •Damaged or cracked tone/reluctor ring teeth on the hub or axle
- •Faulty or worn left front wheel speed sensor
- •Excessive air gap from a loose sensor or worn wheel bearing
- •Corroded or loose sensor connector at the wheel
- •Chafed, pinched, or broken sensor wiring near the strut
- •Mismatched or incorrect tire size affecting signal plausibility
C0051 on Ford by Model
Ford Escape(1 issue)
- Electric Power Steering Rack Failure2013-2022
The 2013-2022 Escape uses an electric power steering (EPS) rack that can fail, causing heavy steering, intermittent loss of power assist, or a steering warning light. The EPS motor or torque sensor within the rack assembly can malfunction due to heat and electrical issues. When the system faults, the steering becomes extremely heavy and difficult to turn, especially at low speeds. This is a safety concern particularly during parking maneuvers.
Ford Fusion(1 issue)
- Electric Power Steering Rack Failure (Recall 15V340)2011-2013
NHTSA recall 15V340 covers 2011-2013 Ford Fusion (and Lincoln MKZ) without the 3.5L engine. An intermittent electrical connection in the steering gear can cause sudden loss of electric power steering assist while driving. Owners notice heavier steering effort especially at low speeds, increasing crash risk. Dealers check the Power Steering Control Module (PSCM) for DTCs; if any loss-of-assist codes are stored, the steering gear is replaced free. Note: 2010 Fusions had the same parts but were excluded from the recall — feds closed the probe without expanding scope. 2010-owner symptoms are real but uncovered by recall.

What does C0051 mean on Ford?▼
C0051 stands for "LF Wheel Speed Sensor Circuit Range/Performance." C0051 is a chassis/brake code meaning the ABS module is reading an unreliable or out-of-range signal from the Left Front (LF) wheel speed sensor. The sensor counts how fast that wheel turns by sensing teeth on a tone ring, and the computer expects its signal to track logically with the other three wheels. When the LF reading is erratic, intermittent, or doesn't match vehicle speed, the module sets this 'range/performance' code. It generally means the data is present but doesn't make sense, which can disable ABS, traction control, and stability control until corrected. On Ford specifically, this code is documented across 2 models.
What causes C0051 on Ford vehicles?▼
Common causes on Ford: Metal debris, rust, or brake dust contaminating the LF sensor or tone ring, Damaged or cracked tone/reluctor ring teeth on the hub or axle, Faulty or worn left front wheel speed sensor, Excessive air gap from a loose sensor or worn wheel bearing, Corroded or loose sensor connector at the wheel. Specific causes vary by model and year — see the per-model sections below.
