Delphi ABS Wheel Speed Sensor P/N:SS21389
Delphi SS21503 sensor for the 2020-2024 Tesla 3 and other vehicles is a front ABS wheel speed sensor that reports each wheel's speed to the ABS.
A lit ABS or traction control light can mean a wheel speed sensor is failing. The light alone does not prove the sensor is at fault, since a damaged wire in the harness can set it off too. This listing is one sensor, and both front sensors are normally replaced together.
It is also a direct-fit replacement for the 2020-2022 Tesla Y.
