Santa Fe V6-3.5L (2004)
Vehicle Speed Sensor: Description and Operation
CIRCUIT DESCRIPTOR
The vehicle speed sensor which is installed on the speedometer driven gear in the transaxle provides a pulse signal to the ECM, and the ECM calculates
the vehicle speed. In addition to the vehicle speed sensor, a wheel speed sensor which is installed on the right front wheel provides a direct analog pulse
signal to the ECM, and the ECM calculates the vehicle speed.
With the ignition switch in ON or START, battery voltage is supplied from fuse 25 to the vehicle speed sensor (VSS). The sensor is grounded at
G02(V6)/G03(l4).
The vehicle speed sensor (VSS) intermittently grounds the circuit, which generates a pulse signal in it. The number of pulses per minute
increases/decreases with the speed of the car.
