Rs tuner fault code

[M-H 182]

I've got a fault code on the RS tuner -
'DF0007 - internal Temperature sensor - open circuit'

Is this the coolant temp sensor? It's being flagged up by the 'HVAC' (Climate control) ecu, not the 'ECM - engine control module'.

behind the interior light.

It's probably been unplugged as they buzz away once worn
