Seat Track Position Sensor
WARNING: This page is about a different car, the 2002 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.
The seat track position sensor is located under driver front seat, on outboard side of seat track. Seat track position sensor informs Restraints Control Module (RCM) of left front seat position. RCM uses seat track position sensor inputs to determine deployment rate of dual-stage driver and passenger air bag modules.
