Hi all, my name is Dennis and I'm a newbie to the forum. I recently put my Ody back on the road after sitting in the garage for the last 7 months. After which, the van is kicking out an error code P0560, low backup voltage to the ECU. Does anyone have any experience with this code? The van is also kicking a 1494 code. I removed the intake and cleaned the EGR ports and valve head and am still getting the EGR code. I think it might be related to the low voltage issue but not sure. I've cleaned many of the main grounds and had the alternator tested.

2001 Odyssey with 180K and has spent most of its life in Buffalo so I'm thinking it might be a corrosion issue. I've looked on the net for info, but haven't been able to locate any helpful info. Where exactly is the ECU located?

Any help would be great! Thanks in advance.
