The FSM has a very detailed section on testing sensors... especially for the ECCS (turbo) system. Obviously you don't jam the multimeter probes into the ecu plugs. 
Use a thin gauge wire to jumper between the ecu pin and the multimeter probe. On one of my multimeters I stripped down some telephone wire, wrapped one around each probe, and then cut them at about 10".

What do you think about my testing of the O2 sensor? Should it have read something at that temperature? I think my exhaust pipe was ~ 400degrees.. I heard somewhere it might need to be at 600.
