Position Sensor: Operation
WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
During normal vehicle operation, the Powertrain Control Module (PCM) monitors the transfer case position sensor return voltage to determine the operating mode of the transfer case. Refer to OPERATING MODE VERSUS RESISTANCE . table for the correct resistance for each position. See Fig 1. Note that the NEUTRAL position is allowed to float between sensor positions 3 and 4. If a resistance is measured anywhere in either range, the sensor is operating correctly.
