So, I've gotten virtually nowhere with this. The dealership told me the intake valve and gaskets were bad, so they sent a claim to my warranty company. A week went by and I hadn't heard anything, so I called. The warranty company said the dealership failed to show the claims adjustor that there was a failed part. I asked the dealership about this and they said they showed the adjustor everything and the adjustor said "I don't see why this WOULDN'T be covered". So yeah, I dont know who I'm supposed to believe.

I just called back the dealership today and they gave me a list of "recommended" repairs:
-IMRC valve
-Bypass actuator (including upper manifold cover gasket, bypass valve actuator gasket, and bore plate seal)

They never referred to the repairs as "recommended" until now. But also, the warranty company has been shady in the past as well. The dealership told me the P2195 code was because some wire was left unplugged when the O2 sensor at bank 1, sensor 1 was replaced. According to the warranty company, the dealership submitted a claim to REPLACE the O2 sensor. I asked for them to e-mail me a copy of the claim, so I can take it up with the dealership.

What do you guys think about this? What should I do? The dealership said since the gaskets are bad and have now been removed/re-installed i really need to get them replaced ASAP (which makes sense). Should I just go back to my old service tech to see if they can confirm anything the dealership said? I already paid the dealership $100 for diagnostics, and taking it to my other service tech would run at least another $60 for diagnostics :/

Not sure what you want here, so I have some questions.

Is the warranty company going to pay for the repairs? Did the dealership do the software update in the TSB?

The repair items are just replacing the intake manifold gasket(s) and the IMT actuator? Avoid calling the IMT actuator an "intake valve", because an intake valve has a much different meaning.

No, the warranty company will not pay. What I gathered from there adjustor's report is that nothing actually failed...the gaskets/seals just need replacing. These third party warranty companies wont cover non-failed parts.

The dealership did not do the software update. I had asked again and did not get an answer again. I'm so fed up with talking to them, I almost dont even care about that.

"Intake valve" is what the dealership told me, even though its not what appears to be the issue. I really don't know anything about this stuff, so my apologies if I'm screwing up terminology.

Here is the receipt from the dealership and the adjustor's report. Maybe you could explain what I need to replace?

Here is what I have gathered. The dealership fixed the O2 sensor by properly plugging it in.

The tech could not get the CEL to turn on when the adjuster was there. He also could not prove that the valve was bad. It reads like the tech did read the CEL code P1078 at some point, but not when adjuster was there.

The tech recommended that the IMRC valve bypass actuator be replaced. There are seals that would need to be replaced when you go to replace that part.

Has the CEL turned back on? How is the car driving?

I would call Honda of America. There is a TSB for the P1078 code. The tech noted the P1078 code, but did not follow the TSB. I think that Honda should have the dealership service department to the TSB fix.

I may be wrong; but, this is how I am seeing it. The regular factory service warranty (via Honda America) has expired. You purchased an extended warranty through a third party insurance company.

Since the regular warranty is over, the dealer does not want to perform a service which they may not get paid for (e.g., software update). When you paid for the diagnostic fee of $90, the dealer tech essentially divided the time for both trouble codes. The tech fixed the O2 sensor issue and believes the IMT actuator, gaskets, etc. need to be replaced. The third party insurance adjuster wants the dealership to prove the part was defective. The tech probably declined to conduct further diagnostic (e.g., more scan test, etc.), as they may not get paid for it.

Well, it says on the TSB that if I'm out of warranty, I may have to pay for a software update. I told the dealership this; I told them I'd pay. But they're still giving me the runaround. And paying $90 for diagnostics that I already knew is BS. The clip was stuck on the sensor, ok, that was a help. But its not like it took them more than 30 seconds to fix that...its right in the front within arm's reach. I haven't tried repulling the codes yet. But I dont think the warranty company is paying for anything no matter what.

Was there any recent work performed prior? (i.e., did the private shop you mentioned perform any knind of work that required the air plenum to be removed?) If they removed the intake plenum and did not set the IMRC correctly upon installation it will throw the CEL P1078. I have this code recently on my 04 Accord- however I did a complete engine rebuild and wasrequired to remove the IMRC to parts wash the intake components. Unless the IMRC is improperly set (the stepper motor's gear meshing correctly with the quarter of a gear on the valve itself), or their is a voltage coorelation to the IMRC, it should not throw the code you are seeing. Because I doubt the IMRC was unplugged or damaged without reason, I would investigate what work was done.... and you mentioned the dealer said the gaskets were worn but reinstalled? Were they reinstalled y the private mechanic? That is a shade tree mechanic mistake and you might take up arms with that guy to get your money back...
