Vehicle Speed Sensor/Transducer - Cruise Control: Description and Operation
VEHICLE SPEED AND DISTANCE-PCM INPUT
The Vehicle Speed Sensor (VSS) is no longer used for any Dodge truck in the 1998 model year.
Vehicle speed and distance covered are measured by the Rear Wheel Speed Sensor. See: Sensors and Switches - Brakes and Traction Control/Wheel
Speed Sensor The sensor is mounted to the rear axle. A signal is sent from this sensor to the Controller Antilock Brake (CAB) computer. A signal is then
sent from the CAB to the Powertrain Control Module (PCM) to determine vehicle speed and distance covered. The PCM will then determine strategies
for fuel system and speed control system operation.
