Temperature sensor on ADC2

Hi everybody.

I've just a little question : does anyone knows if the internal temperature sensor of an STM32F107 can be read with ADC2. In the reference manual it's written "The temperature sensor is internally connected to the ADCx_IN16 input channel" but on figure 39 Vsense and Vref are clearly connected to ADC1.
However I'm trying to use ADC2 to read internal temperature sensor value but I just get very very low values (0x01...0x07) while with ADC1 values are Ok.

Thanks a lot.
