Fault codes

[Mike Del Tergo]

Bernies' comments echo my findings.  I tossed a slightly used O2 sensor in.  
New temp sensors were not immediately avail and I did not want to drop a new 
O2 in while still having a "bad" IM temp sensor.  No iimediate change in 
codes.  Next day, all codes gone and car is happily flashing 4444.  I never 
get the all clear codes in the 200, usually always have the 2111.
We'll see how long it lasts!
