Tesla Model 3 & Model Y Rear ABS Sensor – Left / Right
This rear wheel speed (ABS) sensor is a Febi 193657 replacement for the original Tesla part. It reads the speed of the rear wheel and sends the signal to the ABS, traction control and stability systems. The same sensor fits the left or right side, and it is sold singly.
A failing wheel speed sensor usually shows up as an ABS or stability warning light, traction control that cuts in at the wrong moment, or a wheel speed fault stored in the car’s log. Damage often comes from road debris, corrosion at the connector or a cable that has been pulled or chafed during other suspension work.
On the Model Y Dual Motor and Model Y L Dual Motor, this sensor is listed for vehicles without Performance brakes, so check the notes in the fitment table if your car has the Performance pack. On the Model 3 a few versions are listed with a specific motor code, also shown in the table.
