The 156 does not have a CAN bus (also not the V6)
As far as I know, the 156 ALWAYS has a seperate temp sensor for the gauge, independant of what is measured by the ECU.
However, the 2 temp senders are mounted in the same physical plug, with one electrical connector, on the thermostat housing making it look like 1 sensor.
The one going to ECU is a 2-wire connection, the one to the gauge is a singe wire (and ground).

see (K36 is combined temp sensor) :
