Gear Sensor/Switch: Description and Operation
NV242 - Transfer Case
NV242 Transfer Case
DESCRIPTION
The transfer case position sensor (Fig. 98) is an electronic device whose output can be interpreted to indicate the transfer case's current operating mode.
The sensor consists of a five position, resistive multiplexed circuit which returns a specific resistance value to the Powertrain Control Module (PCM) for
each transfer case operating mode.
The sensor is located on the top of the transfer case, just left of the transfer case centerline and rides against the sector plate roostercomb. The PCM
supplies 5VDC (±0.5V) to the sensor and monitors the return voltage to determine the sector plate, and therefore the transfer case, position.
OPERATION
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.
