Matco Maxmus evap function test HELP???

I have a matco maxmus I'm trying to Diagnose a evap code p1457 on a 2003 Acura 3.5 rl when i go under the evpa function test it will let me control the 3 valves but will not to a self function test like the snap-on tools ! What I would like to know is it  self function test under self function test under a different part of the program or it's just not able to do this type of test ??? I would all so like to know is it under the data readings some of the sensors are in different measurement that what I need to know I would like to know if im able to change that and how to. For example the fuel tank pressure sensor is reading in kpa and I need to know what its reading in volts to see if its in the proper range the kpa reading don't help me at all. I will try to post some pics so you can see what Im talking about. Any help that you guys can give me I would rely be a big help to me.
