Hyundai Elantra HD: Seat Track Position Sensor (STPS). Description and Operation
Description
The STPS operates via a non-contacting magnetic proximity
sensing device combined with a simple electronic circuit resulting in the ability
of producing two separate and distinct logic level signals.
The STPS output signal is altered by the proximity of a separate
ferro-magnetic shunt, which is linked via the seat track. The logic signal produced
is the result of the proximity device being activated or deactivated.
When the seat is in the forward position zone of the track,
the sensor gives a low current (prohibit) signal. When the seat is in the rear
positon zone of the track, it gives a high current (enable) signal.
