PAT Wheel Speed Sensor WSS-385 LHF

The PAT Wheel Speed Sensor WSS-385 LHF is essential for the operation of intelligent safety systems and other vital vehicle functions. Originally introduced for Anti-Lock Braking Systems (ABS), these sensors are now integral to numerous modern vehicle systems. - Crucial for driving safety, influencing systems such as ABS, TCS, ESC, ADAS, and ACC - Supports engine management, transmission control, and navigation systems - Significantly impacts vehicle dynamics, driving comfort, safety, emissions, and fuel consumption - Available in two types: passive (inductive) and active - Active sensors offer accurate wheel speed detection from stationary, crucial for traction control and hill descent control - Smaller and lighter design with insensitivity to vibration and temperature fluctuations - Reduced electromagnetic interference and ability to detect forward and reverse movement Symptoms of a faulty wheel speed sensor include multiple warning lights on the dashboard, wheels locking during braking, pulsation of the brake pedal, erratic or no speedometer operation, and other seemingly unrelated system failures. For effective diagnosis, use a suitable diagnostic tool to read fault codes, inspect the wiring and mechanical assemblies, and check the output signal, supply voltage, and sensor resistance as needed.
