Help with pulled codes. EBPV?

[The_Mule]

I pulled P0470 - exhaust back pressure sensor ciruit error
and P0478 - exhaust pressure Ctrl valve high input.

Has my EBPV gone bad?
Is there a cheap fix like a sensor to replace, maybe EBP sensor?

If not, I'm thinking of removing it, and found some replacement parts rather than just gutting it.
Garrett Non-EBPV Cover Plate Mfg Part # GA-4512740005 and
Garrett Non-EBPV Pedestal Mfg Part # GA-7026700002 from Long Island Island Performance Diesel

Will I need both the cover plate and the pedestal to correctly eliminate it? Will this fix my problem and cure the codes? I also thought about a banks power elbow, but I already have a 4" turbo back downpipe and exhaust and I'm not sure if it will be conpatible?

Any help or suggestions would be appreciated.

Thanks,
-Carl

You may want to simply pull the sensor and tube. Check to see that they are not plugged with soot which has been know to be a problem. Blow compressed air through the tube or run a wire through it and make sure that the sensor's open end is not closed up.

I pulled the EBP sensor tube and found it has a hole in it

What problems will this cause givin it's connected to the exhaust manifold? Should I get a new tube or patch it somhow?

A hole in it is about the same as being plugged. The sensor can't read the pressure that is really there. It shouldn't cause any permanent damage as long as you get it replaced soon.

Patch won't hold, it'll just open somewhere else if it has corroded that badly. You will have to get a new one and from what I understand, don't let the stealership see how much you have in your wallet. Online vendors will be cheaper if you have time to wait.
