Low Boost, Got Codes

[Got Diesel]

Ok I only hit max 20 psi, usually only about 15 psi. Obviously Boost leak or something else. My up-pipes have soot on them, I am pretty sure that this is the boost leak.

The codes that I get are:
P0603
P0478
P0470
P1211

What do these mean, could any of these be the culprit? Thanks

here is the wiki that explains all the codes

Thanks for the link, could any of these be the culprit of the low boost.

well, I really dont know. I just knew that link was there but I know very little about low boost other than possible line leaks or boot leaks. Im sure someone will post up soon. Sorry I cant help more.

P0603 Internal Control Module Keep Alive Memory (KAM) Error
normal for a chip or tuner

P0478 Exhaust Pressure Control Valve High
P0470 Exhaust Pressure Sensor Malfunction
P1211 ICP Not Controllable - Pressure Abow/Below Desired

wow what did you DO

Might be the 470, and 478... these are exhaust back pressure codes, the sensor is located up by the water pump, and has a tube that runs to the passanger manifold. This tube gets clogged sometimes and can cause low performance.

The ICP is also the norm with a chip or tuner... The tune is asking for more HPO then the pump can give.

I would be it is the 470 and 478 as well. The tube can also just rust out and get holes in it which will cause problems.

Ok so I took out a wrench and then tightened up all my intercooler boots. I felt around my up-pipes and didn't get any soot on the fingers, when looking at the firewall there is no soot. So I don't know what to say about the up-pipes. I then went for a test run, wot coming up a grade hit 21-22psi, I think that the slow climb may be due to the stock downpipe. What do you all think?

Should I take the tube off and try and clean it?
