Engine code P1600 and P1449

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!

TAKE IT TO A DEALER, RECENT SERVICE NEWS, HONDA WANTS TO LOOK AT YOUR HYBRID

SOURCE: Honda code P0A7F

I have a 2006 Honda Civic Hybrid and have had hell with it. I have also learnt much about it too.

One thing bad about the HCH2, is that the 12V battery controls the electronics, and the Hybrid battery charges the 12V battery. However the 12V battery is not charged all the time, and cannot be charged when the IMA is usually being used, and in different scenarios. (Buy a Electronic volt meter which plugs into the 12V adapter $14 Walmart))

It is possible that the 12V battery is being drained while driving and caused a voltage drop which can cause your problem. In your case, I would change the 12V battery anyway as they do not last long on Hybrids. (You may have to get Honda to trip the IMA warning lights.) In my case, changing the 12v battery helped the hybrid battery as it was the electronics reporting the charge level wrong.

Depending where you live, you will have a minimum 80,000 mile warranty on the hybrid battery.

You should have it checked by a qualified tech. Auto zone dont do diagnostic repairs, they can only give you trouble codes.
