Interior Temperature Monitoring
WARNING: This page is about a different car, the 2004 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
The EATC control module monitors the interior temperature through a sensor system consisting of four sensors. Two sensors in the heater housing for monitoring the outlet temperature, one sensor in the EATC control panel to monitor the interior temperature and one sun load sensor in the crash padding to monitor the intensity of the sunlight entering the vehicle. In addition, the EATC control module is supplied with the current external temperature information by the trip computer. On vehicles with a Duratec-ST engine, the EATC control unit is supplied with the current exterior temperature information over the SCP-Bus.
