Circuit Description

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(I4)/G22 (Diesel).

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.
