Hyundai Elantra: Seat Track Position Sensor (STPS). Description and Operation - SRSCM - Restraint - Hyundai Elantra MD 2010-2018 Service manualHyundai Elantra: 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.
