Vehicle Speed Sensor:
VEHICLE SPEED SENSOR
The Vehicle Speed Sensor (VSS) is a pulse generator mounted in the transaxle. A toothed reluctor ring rotates near a magnetic pickup which produces a varying voltage signal in the pickup coil. This voltage signal varies in proportion to vehicle speed and is sent to the PCM, where it is converted to MPH.
PCM INPUT
The PCM uses VSS information for fuel economy calculations, idle speed control, transaxle shifts, and to control fuel under certain conditions. A faulty VSS may cause various transaxle and engine driveability conditions and should set a PCM Diagnostic Trouble Code.
