Since the manual mentions two channels and a phase difference between them, I wonder if it's an incremental rotary encoder (http://en.wikipedia.org/wiki/Rotary_...tary_encoder)?
These just may be repairable.

Ok so I'm going to open the SWPS up. I see a glossy border shown in the pic below, looks to be some kind of adhesive, I think I'll start by removing that and seeing if I can get this apart without destroying it

The new sensor comes fitted with a pin which makes sure it's installed in the correct alignment on the shaft. The pin is removed once the sensor is fitted. This is to make sure the correct voltage is output when the steering wheel is on center.
If it is repairable, you'll need to work out whether its just a case of reinserting a pin to re-align it.

sorry guys I don't really have time to explain my findings right now, but I figured I'd post up the pics.
this last pic is the area underneath the connector pins, there is a small PCB there and just above is some type of sensor? I'll take that apart later and explain a little more when I have time.

Not alone. See the two circles of tiny slots in the shiny metal ring in pic 1? Those are typical for an encoder. I wouldn't be surprised if you'd find two optical interruptors on that PCB, each for one row.
It also looks like the pot is directly driven by the steering shaft (the metal contact in pic 3 slides over the large PCB in pic 4) - no idea what those gears are for...

The steering shaft drives the middle gear which drives the smaller gear (partially visible) which has a little gear on the bottom of it (you can't see) which drives the large gear.
The POT could be measured by itself.
Interesting.

depends upon the resistance values of the newer sensor, I assume they are different hence the different part #'s. I suppose manufacturers could have been switched, I don't know? if I can find a newer sensor I can compare the two.
