I am assuming the T EPTEP 36, a temperature sensor is a sub on the schematic for the pressure sensor. If so per the schematic and the data sheet you should be all set, the device works at 3.5v and 5V. Running both at 3.3 volts as your schematic shows will be fine. I would also recommend you add some bulk and high frequency bypass capacitors on the VCC supply (Vin & Gnd), something in the 100nf and 4uf range.
