Replacement RF31080040 Front ABS Wheel Speed Sensor OEM# JL3Z2C204D

The Replacement RF31080040 is a front ABS wheel speed sensor engineered as a direct OEM replacement, cross-referencing Ford/Motorcraft part number JL3Z2C204D (also supersedes FL3Z-2C204-A, FL3Z2C204A, JL3Z-2C204-A, JL3Z2C204A, and ALS2696). Designed for front-axle applications, this sensor serves both the driver and passenger sides interchangeably.

The wheel speed sensor monitors individual wheel rotation rates and transmits that data to the vehicle's electronic control unit (ECU). This signal is critical for the proper operation of the Anti-lock Braking System (ABS), Electronic Stability Program (ESP), and traction control system. A failing sensor can trigger ABS or traction control warning lights on the dashboard, cause wheels to lock during hard braking, or produce speedometer irregularities.

Key Features:

• Direct OEM replacement — meets or exceeds original equipment specifications
• Fits front left or right (driver or passenger side) — one part number for both positions
• Includes ABS wheel speed sensor wire harness
• Wheel-mounted design; mounts to the stationary hub assembly and reads from the reluctor ring
• Restores proper ABS, traction control, and electronic stability system function
• Compatible with 2WD, 4WD, and RWD configurations
