look here for these codes http://guzzle.rbmicro.com/dtc1.html
472 and 475 are ebp sensor codes( your ebp tube is probably clogged)
238 is turbo high input( could be set from above or could be the Predator)
and 603 is a KAM(keep alive Memory) have you disconnected your batts latley?

they could off disconnected my batteries for the trans rebuild so the ebp is in the front of the moter not the one back by the turbo i alvest get those confused could that be why it does feel a tad sluggish

I get 0475 code from my hypertec program,no matter what I can't get it to go away with the program in it anymore
it don't seem to hurt anything been there for a couple years and truck runs and pulls good

there are couplers on both ends of it, one on the exhaust manifold, one under the sensor. PB or liquid wrench the crap out of them and carefully try to loosen them. If they wont come undone you can remove the sensor and run some heavy gauge weed eater line through it and ream it out. Then maybe replace the sensor, if it needs it. Mines an 02 just turned 100 and i dont think mine was ever cleaned but it was blocked off right under the sensor, got maybe 1-2 mpg back. but other than that it think it mostly controls the fuel mixture. I know it has a default setting in the PCM but having it function properly would probably lose the code.
