differential pressure regulator data- now I'm confused

[Brian Devlin <bdevlin@stanford.edu>]

I put the ameter on my differential pressure regultator, here's what I got (plus my O2 sensor data

rpm		throttle	o2 volts	DPR mA
cold start		closed	0.5	>50- momentary, then goes to 13-15
idle		closed	0.2-0.7	13-15
1000-2000	closed	0.7-0.8	20-25	(decelerating)
2000-3000	closed	<0.1	20-25	(decelerating)
3000-4000	closed	<0.1	20-25	(decelerating)
1000-2000	part	0.2-0.7	~15
2000-3000	part	0.2-0.7	~15
3000-4000	part	0.2-0.7	~15
1000-2000	wot	varies	13-15
2000-3000	wot	<0.1	13-15
3000-4000	wot	0.7-0.8	13-15

Here's why I'm confused:
I know that if the you pull the "spare fuse", the car will not run because it is too lean (put a fuel soaked rag in the intake, and it idles fine). 
I thought that this was because there is no juice to the pressure regulator, since pulling the plug recreates the same problem.
Therefore I concluded that current open the regulator, allowing more fuel into the engine.

As you can see above, when I'm decelerating and the fuel gets cut off, the current is HIGHEST (other than start).

I'd assumed that the regulator is the only way the computer can alter the mixture. 
So...either 
I'm totally confused about how the thing works, and high current closes it?
OR 
There is another way for the computer to cut off the fuel. Maybe the fuel pump is shut off and the higher current is just an attempt to restore normal mixture?

On another I got two suggestions to check the temp sensor:
One guy said 2,500 ohms at 60 deg. C and lower resistance at higher temps.
Another guy said 900-1.3K at 60 deg F.
I measured 3900 Ohms at 60deg F, and around 200 at running temp.

Which one is right?
