Passenger Compartment Temperature Sensor (ECC Only)
The passenger compartment temperature sensor is behind the dashboard environment panel on the left-hand side. The climate control module (CCM) (for ECC) receives the value indicating the present passenger compartment temperature from the sensor. There is also a fan on the sensor. The fan supplies the sensor with air from the passenger compartment. This prevents the value from the sensor from being distorted by heat generated by surrounding electronics.
The passenger compartment temperature sensor and fan are directly connected to the climate control module (CCM).
There are diagnostics for the passenger compartment temperature sensor and fan.
