Safety Warning

Sensor, Seat Track Position: Description
The Seat Track Position Sensor (STPS) (2) is a Hall Effect-type sensor used on some vehicles. 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 STPS housing has a mounting slot containing an integral latch feature (1) and slides and latches onto a stamped metal blade-type bracket located on the inboard side of one of the upper seat adjuster tracks near the rear of the driver side or passenger side front seat. A molded connector receptacle (3) integral to the STPS housing is connected to the vehicle electrical system through a connector and take out of the front seat wire harness beneath the front seat cushion frame.
The STPS cannot be adjusted or repaired and, if ineffective or damaged, the entire STPS unit must be replaced.
