@nihautos: ABS Speed Sensor (Wheel Speed Sensor) • Function: • It monitors the rotational speed of each wheel. • Sends this data to the ABS control module. • The module compares wheel speeds; if one is about to lock up under braking, it reduces braking force to that wheel. • Other Roles: • Provides speed data for traction control and stability control (ESP/ESC). • Supplies vehicle speed info to the instrument cluster and sometimes the transmission ECU. #automotive #automobileengineering #automobile #autoengineering #carwiring
