Code B105A Lincoln Description

The in-vehicle temperature and humidity sensor contain a thermistor and a sensing element which separately measures the in-vehicle air temperature and the humidity, then sends those readings to the FCIM. The in-vehicle temperature and humidity sensor has an electric fan within the sensor that draws in-vehicle air across the two sensing elements. The FCIM may adjust the actuator doors based on the in-vehicle temperature and humidity sensor information to maintain the desired humidity and temperature of the passenger cabin air. The Front Controls Interface Module (FCIM) monitors the Cabin Temperature Sensor Fan. The FCIM sets the OBDII code when the Cabin Temperature Sensor Fan is not to factory specifications.
