Looks like some electrical short on the engine or around the DME is messing up the system. The fault is not necessarily related to the sensors listed.

Thanks alot. Was thinking the same thing. I have actually replaced the cranskshaft sensor as well as the 2 turbo cooler sensors. Still no luck.

Get an electrical diagram and start measuring the voltages on the misbehaving sensors, that could lead to the problem. I heard Ista Rheingold has the diagrams.

So I ran a scan again with an Innova Scanner to get more common generic codes to see if anyone has experienced any of the issues.
Here are the codes.

P0727 - Engine Speed Input Circuit No Signal
P0241 - Turbo/Super Charger Boost Sensor B Circuit Low
P0237 - Turbo/Super Charger Boost Sensor A Circuit Low
P0370 - Timing Reference High Resolution Signal A
P0030 - HO2S Heater Control Circuit (Bank 1, Sensor 1)
U1164 - Message Monitoring Engine Control Check Sum Error

Any help/info will be appreciated.
