First of all its a 2001 couple LX 4cyl

So my accord started throwing a CEL p0560 which translates to low backup voltage to the PCM. Well the wire that sends the backup voltage is yellow white with silver stripes. And it is connected to fuse 13 clock/backup located in the passenger side fuse box. Anyways so the clock is working just fine, i found the white yellow wire connected to the PCM tested it no voltage! Next i unplugged connector b from the fuse box. The white yellow wire is located in that harness i tested the continuity from the fuse box to the white yellow wire in the PCM harness it is good, for some reason it wont carry voltage though. I even took some alligator clips and connected a 9v to the fuse box then tested the voltage at the PCM harness still nothing. I am thinking i may just need a new fuse box but id like to test some other stuff first. Does anyone know where to get really detailed wiring diagrams because the haynes book sucks. Id like to be able to trace the whole yellow white circuit.

Just buy the Helm factory service manual:

and/or the Helm electrical troubleshooting manual:

It's the best money you can ever spend on a vehicle if you intend to repair it yourself.

I have attached the related diagrams for the model you questioned. Hope these will help. I did not find any YEL/WHT wire. I only found WHT/YEL wire witch connects the VBU pin of PCM with #13 fuse in passenger side.

Good luck.
