Anyway, just as the previous owner had told me, that CEL would come on every now and then, but not frequently. I would go months without it showing back up after I cleared it with my Durametric. Lately it's coming on every couple of days.
The two codes are the P0430 and P0197 (oil temperature sensor below specified value).
These codes never show up separately. Every time the CEL comes on, I get both codes, and always the same two.
I've read a lot of threads now, and I'm not sure where to go from here.
What values should I look at in the Durametric to help diagnose these problems?

your P0197 code is listed as a short to ground
Going with simplest things first diagnostic principals I would try to find out why the oil temp sensor is throwing a code.
It could be a wiring issue some where between the DME and the oil sensor.
It could be a faulty connection in that wiring.
It could be the oil sensor its self.
Point is find and fix the oil senor issue first. It should be simpler, easier and cheaper.
Once that is fixed it could fix the P0430 code as well.
These are just my thoughts and guess's on the issue
