Delphi ABS Wheel Speed Sensor P/N:SS21330
Delphi SS21170 rear ABS wheel speed sensor for the 2013-2019 BMW 640i Gran Coupe 6-cylinder 3.0L and other vehicles tells the ABS how fast the wheel is turning. Delphi builds its sensors to meet or exceed OE requirements and testing.
A lit ABS warning light or an erratic wheel speed reading can mean a sensor has failed. A damaged sensor wheel can light that warning too, so these signs alone do not prove this part is at fault. This listing is one sensor for a rear wheel position; the count per car depends on the model year.
Fitment also covers the 2013-2019 BMW 650i Gran Coupe V8 4.4L and the 2013-2019 BMW 650i xDrive Gran Coupe V8 4.4L. Look up your own BMW's year and engine in the "Vehicles it fits" section.
