Temperature sensor
The air temperature sensor (1), located on vehicle central part, detects the ambient temperature.
The detected signal is sent to the control unit, that shares it through the CAN line with the instrument

Check the operation of sensor (1) using the DDS 2.
After selecting the proper items on the DDS 2 menu, read the external air temperature value among the
different displayed parameters and compare it with the actual value. Change the sensor if reading is
