- Well, to start there are a number of different types of sensors and most are used by multiple vehicle systems. Modern vehicles use multiplexing to share vehicle speed information between modules. For example, the Variable Assist Power Steering (VAPS) system uses Vehicle Speed Sensor (VSS) input to regulate power steering pressures for higher assist at slow speeds, making parking lot maneuvers easier to perform. The Anti-Lock Brake System (ABS) uses VSS information to determine when a wheel is locked up and releases pressure to that wheel to maintain directional stability. Some vehicles use separate sensors for the ABS, but it is common that the computer uses the information from the wheel sensors to act as a VSS. For example, many newer Ford vehicles use a rear axle mounted speed sensor for both ABS and computer related vehicle speed functions. Instrument Cluster (IC) and Hybrid Electric Cluster (HEC) modules use vehicle speed info for speedometer operation.Many advanced air suspension systems use VSS output to determine ride height. These vehicles are lowered at higher speeds for improved handling. Transmissions rely on VSS information for shift strategy. Cruise control systems rely on the VSS for knowing when to activate and deactivate the system and also to maintain a constant speed. All Electronic Engine Control (EEC) systems utilize speed sensor information in one way or another. The list goes on, but I'm sure we can understand the importance of this sensor's correct operation.
- Most newer vehicle speed sensors are of the permanent magnet type, and function much the same as a camshaft or crankshaft sensor. The sensors can be mounted eith
