Mercedes Sprinter Front ABS Wheel Speed Sensor – GST | NCV3 2500 / 3500 | #906540031764 (2007–2018)

A failed front ABS wheel speed sensor on a NCV3 Sprinter removes the front wheel speed reference the ABS, traction control, and stability control systems depend on — illuminating the ABS, TCS, and ESP warning lights simultaneously and disabling the safety systems that prevent front wheel lockup and loss of directional control during hard braking. This is the GST front ABS wheel speed sensor for NCV3 Sprinter 2500 and 3500 models, fitting both left and right front positions, a direct replacement that restores accurate front wheel speed measurement and full ABS system function.

What This Part Does

The front ABS wheel speed sensor is a Hall-effect sensor mounted at the front steering knuckle that reads the teeth of a reluctor ring rotating with the front wheel hub, generating a digital pulse train proportional to front wheel rotational speed. The ABS control module monitors this signal continuously at all four corners — the front sensors carry particular weight in the ABS calculation because front brakes generate the majority of total stopping force. When the sensor fails, the module loses its speed reference for that corner and disables the entire ABS/TCS/ESP system as a safety measure. On the NCV3 Sprinter's front axle, the left and right front positions use the same sensor part number, meaning one part number covers both front positions.

Common Symptoms of a Failing Front ABS Sensor

• ABS, TCS, and ESP warning lights illuminated simultaneously
• ABS fault codes for a front wheel circuit confirmed by scan tool
• ABS activating during normal stops where it should not — erratic sensor output
• No ABS activation during hard stops where it should engage
• Loss of traction control or stability control response

When to Replace

Replace when the sensor is confirmed faulty by scan tool with active front ABS wheel speed sensor fault codes, after ruling out the reluctor ring and wiring harness as the fault source.
