This is CFM-3 system for Airbus:-
Oil pressure is always measured before the bearings where it is needed.. So, the oil press transmitter for ECAM and Low oil press s/w and oil filter clog s/w are after the main press supply pump and main oil filter before splashing into Fwd & Aft bearing sumps, AGB TGB.
Oil temp sensor for ECAM is the cooled oil after coming out from the oil tank before going to the supply pump. However, there is another oil temp sensor for ECU.
