Specs At A Glance

Good To Know

Q: Why does my ABS light come on after installing a new sensor? A: The ABS module usually needs to be scanned and the codes cleared after sensor replacement. If the light persists, check the connector and wiring for damage.

Q: Can a bad wheel speed sensor affect normal braking? A: It can disable ABS and traction control functions while the light is on. Base braking typically remains, but the vehicle should be repaired promptly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
