Vehicle Speed Sensor - Suzuki WagonR+ RB310 Service Manual

1. A / T VSS
2. Input revolution sensor
3. Shift switch coupler
THROTTLE POSITION SENSOR
This sensor is installed to the throttle valve shaft. Throttle valve
opening signal is transmitted from TP sensor to ECM as voltage sig-
nal. The signal is converted to duty signal in ECM and it is sent to
TCM.

VEHICLE SPEED SENSOR

This sensor is a pulse generator type that detects revolution of the
counter driven gear (vehicle speed) in the transmission case.
The pulse generator is a noncontact sensor consisting of a perma-
nent magnet, coil and gears.
As the gear of the counter driven gear rotor turns, the magne-flux
from the permanent magnet varies and a voltage of the frequency
corresponding to the rotor revolution occurs in the coil. This voltage
is inputted to the TCM where TCM judges the counter driven gear
revolution or the vehicle speed.
INPUT REVOLUTION SENSOR
This sensor is a pulse generator type that detects revolution of
torque converter's turbine shaft in the transmission case.
The principle of operation is the same as the vehicle speed sensor.
SHIFT SWITCH
A shift switch (1) is provided so that the engine can be started only
when the shift lever is in the "P" or "N" position.
