In memory seat systems, what is the purpose of the potentiometer seat position sensors?

• A. To determine seat position
• B. To measure seat temperature
• C. To detect occupant weight
• D. To control seat heating

Answer: (A)

In memory seat systems, you need to know exactly where the seat is so it can be moved to a saved position for each driver. The potentiometer seat position sensor sits on the seat track and provides a voltage that changes as the seat moves. That voltage directly represents the current seat position, giving the control module real-time feedback.

Because the system stores these position values, it can recall a driver’s preferred setting and drive the motors until the potentiometer signals that the seat has reached the saved point. This is why the sensor’s role is to determine seat position and enable precise repositioning.

Other functions like temperature, occupant weight, or seat heating use different sensors and mechanisms, not the potentiometer on the seat track.
