Vehicle Speed Sensor: Description and Operation
VEHICLE SPEED AND DISTANCE - PCM INPUT
Vehicle speed and distance covered are measured by the Rear 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.
