Mercedes Sprinter Right Rear ABS Wheel Speed Sensor – Bosch | NCV3 3500 | #9065401217 (2007–2018)

A failed right rear ABS wheel speed sensor on a NCV3 Sprinter 3500 removes the rear right 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 wheel lockup and loss of control under hard braking or in slippery conditions. This is the Bosch right rear ABS wheel speed sensor with integrated wire harness for NCV3 Sprinter 3500 models, a direct replacement that restores accurate right rear wheel speed measurement and full ABS system function.

What This Part Does

The rear ABS wheel speed sensor is a Hall-effect sensor mounted at the rear axle that reads the teeth of a reluctor ring rotating with the wheel hub, generating a digital pulse train proportional to wheel rotational speed. The ABS control module monitors this signal continuously — when one wheel begins decelerating faster than the others during a hard stop, the module modulates brake pressure to prevent lockup. The sensor includes an integrated wire harness that routes from the wheel hub area to the body electrical connector, and is specific to the 3500 series rear axle configuration. When the sensor fails, the module loses its speed reference for the right rear wheel and disables ABS/TCS/ESP as a safety measure.

Common Symptoms of a Failing Right Rear ABS Sensor

• ABS, TCS, and ESP warning lights illuminated simultaneously
• ABS fault codes for the right rear wheel circuit confirmed by scan tool
• ABS activating during normal stops where it should not — erratic sensor output
• No ABS activation during hard braking 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 right rear ABS wheel speed sensor fault codes, after ruling out the reluctor ring and wiring harness as the fault source.

NCV3 3500 Specific — VIN Verification Required

This sensor is for NCV3 Sprinter 3500 series models with the specific rear axle code (Code BB3). It is not the same as the 2500 rear sensor. Always verify by VIN and axle specification before ordering. Contact us and we'll confirm fitment before you buy.

Fitment

• 2007–2009 Dodge Sprinter 3500 – Rear right, without heavy duty brakes (NCV3)
• 2010–2018 Mercedes-Benz Sprinter 3500 – Rear right, with electronic stability control (NCV3/W906)
• 2010–2018 Freightliner Sprinter 3500 – Rear right (NCV3)

✔ Sprinter 3500 series only — 2500 models use a different rear sensor
✔ Includes integrated ABS wheel speed sensor wire harness
✔ Always verify axle code and VIN before ordering — this part is VIN specific
