Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
