That code represents a lower than expected reading for temperature (coolant). First thing to do is check your coolant level, as if it is low, then the sensor can not read correctly. Second, you may have a thermostat that is stuck open, allowing the coolant to cool off too much. The sensor should be mounted on top of the engine, near the thermostat housing.

the encoder motor sensor is inside the encoder motor. the encoder is located at the transfer case. Remove the encoder and by part number 88962315 this is the sensor. you will have to retime the motor after
hope this helps
