I have been getting the P0406 code (Exhaust Gas Recirculation Sensor A Circuit High) for the longest time but only off and one.
It used to show up for a day and then I wouldn't see it for a few months.
Now it comes and goes pretty consistantly and more frequently.
I am currently at around 118,000+ miles on my car.

I spoke with a Honda/Acura tech friend regarding this and he tells me that usually it is due to clogged ports with in the EGR system.

My question is this... has anyone had this error code and had it corrected by a qualified Auto Technician be it at the dealership or by others.
What did they find and what did they charge?

I have a write up on replacement of the EGR valve on here. Hope this helps

Thank you so much for the link Firedoc.
Although the physical layout may differ from my RT I'm sure that the procedure still applies.

However, that's way more work than I'm willing to do myself.
I was more curious if anyone paid a shop to perform the necessary repairs and how much they charged.

Great "How To" thread tho. I even posted in it but did not remember until I saw it again.

More beans for you!

Thank you so much Tee.
I'm told this mostly just affects your emmissions.
My friend told me that it might keep me from getting smogged when that time comes.

removal

The electronic EGR valve and solenoid assembly (3) is attached to the front of the right cylinder head (1). An exhaust gas routing tube connects the EGR valve to the intake manifold.
  1. Use a diagnostic scan tool to record any DTC's (Diagnostic Trouble Codes).
  2. Disconnect and isolate the negative battery cable.

  3. Disconnect electrical connector (1) from EGR solenoid (2).
  4. Remove two bolts (3) connecting EGR tube (4) to valve assembly.
  5. Remove gasket located between EGR tube flange and EGR valve assembly.

  6. Remove two mounting bolts (2).
  7. Separate valve assembly (3) from cylinder head (1).
  8. Remove and discard metal gasket located between cylinder head and valve assembly.

About 9 months ago, I had EGR codes show for my 2005 SXT. I cleared them and they never appeared again. Looks like you have a different situation, but I do feel that, in some cases, unnecessary work is being done to replace EGR valves etc that are not defective. Looking at other related threads, members have warned against not using genuine oem parts, and making sure gaskets are replaced and seated properly.

Good luck.

Gee, Dave... Posting TWICE in one month???
Nice to see you around. lol
About your "Backing Plate" issue.
Had Gary's remove my left one a few months ago, so I'm just riding around with my right one.
When the right one goes, I'll get a set and get them both installed.
I don't think it will do much harm at all. I think it's more for snow build-up more than anything else.

I had the same issue, replaced it with an aftermarket one, (btw easy job) the aftermarket last a little but got the code back. I was going to replace it with a MOPAR one but cost wise ($135) for the OEM valve, just decided to delete it and had a custom tune written.
But easy job the hardest part is the lower bolt on the valve. If you decide to do it you should also pick up a new egr tube gasket, the tube that goes into your manifold. GL
