Position Sensors

Position sensors are used by memory seat/mirror/steering column modules to store motor positions in memory and return motors to stored memory positions. Each sensor is a potentiometer, and is mounted to each motor's transmission cable. When cable rotates, resistance of potentiometer varies, and feedback voltage is monitored by memory seat/mirror module to determine motor position. The memory seat/mirror module stores motor positions by recording each position sensor feedback voltage. When a memorized position is requested, each motor is moved until the position sensor feedback voltage equals feedback voltage stored in memory.
