2000 Civic Coupe D16Y8 EX

I have the errors code P0138 P0453 I have ohm out all connections
for the EVAP and O2 sensor. I only signal that will not ohm out
is the SG2 back to the C18 pin.

It is connected between C568 pin 6(fuel tank pressure sensor) and C432
pin 2(secondary O2 sensor). No connection back to C18 SG2

Looks like break is between C115(under intake) or C131(right kick panel)

I am trying to find the C131(green connector)

Please take a look an my pictures. Not sure what these connector
are?? Any help or comments are helpful.

UPDATED INFO:
The white connector is C442 Junction Connection
(See included image)

I should be able to find C131 by going from signal A6

Thanks in advance

I am not the original owner of this vehicle.

Look like C131 was removed for whatever reason
I do not know and rewire into the harnesses.

That is why there were some many crimp connectors
on the harnesses. Not a big fan of crimp connectors
probably will remove crimps and re solder all connections.

Found my problem due to an wiring error I had made about month ago
to fix disconnected wires troubleshooting a starting issue.

Car now does not throw any error and runs.
Thanks for all that took a look at this post.

Look into eliminating all of the wire splicing by buying a replacement stock wire harness.
