2018 Mondeo 2.0 TDCI biturbo ECT2 -40C

Hi
Forscan is reporting -40 degrees C reading from ECT2 sensor - but no DTC and struggling to work out if the engine coolant system actually has 2 sensors and if it does, where is it!
ECT1 readings normal.
Regen will start, so doesn't appear to be reliant on realistic reading for ECT2?
Help please!
