My 2005 Civic Hybrid has the same codes. My check engine and IMA lights are on, but the car is running OK.
Did you resolve your problem? Can you tell me what you did?
Thanks,

It turned out to be a failed IMA battery. Honda covered it under warranty, even though the car has a salvaged title, because it is part of the emissions system. A $3000 repair otherwise!
Those codes are thrown when there is a momentary hicup in the electrical delivery from the battery pack. clear the codes and drive it, if they dont come back you are all good, it they do come back then you most likely have a corrosion issue between the battery monitor system and the battery
I had to call Honda Corporate to get them to replace my battery pack. They refused because of my salvaged title. However, the battery pack is part of the safety system and as such overrides the salvaged title, as all safety recalls do. So here we are 5 years later - and the codes are back. I borrowed a handheld code reader from a friend and cleared the codes, but the IMA and Check Engine lights came back up the 2nd time I started it. I am an electrical engineer and am tempted to tear into the battery pack myself. The reader identified the faulty cell.
The good news is, the 2005 Civic runs just fine (and gets almost the same 30 MPG) with this issue. Every model year after is not driveable if this happens. The real issue is getting it smogged next year! Any thoughts greatly appreciated.
