Transfer Case Mode Sensor Signal
WARNING: This page is about a different car, the 2016 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The Transfer Case Mode Sensor Signal Input will provide the DTCM feedback about the position of the transfer case. The mode sensor will be a linear analog position sensor with a 1.4K +/- 20% potentiometer and a 1 K +/- 20% wiper resistor that converts the motor shaft position into a multiplexed voltage.
