Rear Wheel Speed Sensor 3550150-P00-A1

The car wheel speed sensor is a device for detecting the speed of an electronically controlled vehicle. The control computer uses this input signal to control the engine idle speed, the automatic transmission torque converter lock, the automatic transmission shift and the engine cooling fan opening and closing and the cruise fixed speed and Other functions.

The output signal of the car wheel speed sensor can be a magnetoelectric AC signal, a Hall-type digital signal or a photoelectric digital signal. The car wheel speed sensor is usually installed in the transaxle case or the transmission case, and the car wheel speed sensor signal line is usually mounted on the shield. Inside the jacket, this is to eliminate the electromagnetic and radio frequency interference generated by high-voltage electric fire wires and car phones or other electronic devices, to ensure that electronic communication does not interrupt, to prevent poor driving performance or other problems, in the car magnetic And photoelectric sensors are the two most widely used car wheel speed sensor. Magnetic sensors are widely used in various vehicles in Europe, North America and Asia for vehicle speed (VSS), crank angle (CKP) and camshaft angle (CMP). The control can also be used to feel the speed and position signals of other rotating parts, such as the compressor clutch.
