Delphi ABS Wheel Speed Sensor P/N:SS21389
Delphi SS20359 sensor for the 2014-2020 Chevrolet Impala and other vehicles is a rear right ABS wheel speed sensor, which reports wheel speed to the ABS.
A failing wheel speed sensor can show up as an ABS or traction control warning light. A damaged connector or wiring, or a dirty sensor, can give the same signs, so look the sensor and its wiring over with the engine off before you replace it. It is common to change the left and right sensors as a pair, and this listing is one rear right sensor.
It is listed for a wide range of Chevrolet and Buick models, including the 2013-2015 Chevrolet Malibu and the 2014-2016 Buick LaCrosse, with one sensor per vehicle. If your car isn't one of these, enter its year, make and model on the Buyer's Guide tab to see whether it is covered.
