Seat Track Position Sensor: Description
The seat track position sensor (1) is a Hall Effect-type sensor. This sensor consists of a Hall Effect Integrated Circuit (IC) chip encased in potting material within a cavity of the molded plastic sensor housing.
The sensor housing has an integral snap feature (3) and snaps into a stamped metal bracket located on the inboard side of one of the seat adjuster tracks on each front seat, then is secured by a screw into a mounting boss (4) at one end of the sensor housing. A molded connector receptacle (2) that is integral to the opposite end of the sensor housing from the mounting boss is connected to the vehicle electrical system through a connector and take out of the driver or passenger seat wire harness beneath the front seat cushion frame.
The seat track position sensor cannot be adjusted or repaired and, if ineffective or damaged, the entire sensor must be replaced.
