P0405 Code - Is EGR valve always bad?

Well, I have the P0405 code active on my 06 6.0.

I removed it and cleaned it. I have about 130k on the truck and never had to do anything internally to the engine.(knock on wood) I do run Hot Shot secret in the oil. The EGR valve was partially sooted up, but it did not seem as bad as some that I have seen online.

I checked the resistance of the various pins.
Quote:
Pins B and C: 50-2,500 ohms
Pins C and D: 2,000-7,000 ohms
Pins B and D: 3,000-7,000 ohms
and all 3 readings where in spec, but the code is still active. I also vacuumed out the hole in the intake before I re-installed it.



So far, the only symptoms I can say that I see is at highway speeds, when the engine/trans downshifts on inclines, it seems to bog down a little more and puts out more black smoke than before. Other than that, I see nothing different when driving it.


So, is there anything else I can check before I get a new EGR valve?
Any brand of valve better/worse than others?

What problems will happen if I don't install the EGR valve and fix the code?
Thanks

If you have 130,000 miles on the egr valve, you got your moneys worth, just replace it with a new ford egr valve.
