HondaLou,
The answer you seek is on the wiring diagram. See the diagram on page 20-6 labeled CB1100SA (AFTER '13 MODEL)
Look at the bottom of the page and find the EOT sensor. Follow the R/Bu wire and it goes directly to the ECM pin B27 and is labeled TO. The G/O wire goes to a junction block to a group of wires that are connected to chassis ground (the one closed to the Horn High symbol)
From the ECU it gets sent by the serial data line to the meter.
For oil pressure the diagram shows it only going to the meters. There is no mention anywhere of it going to the ECU or having a fault code for it. I think that the meter handles that with the light. Either you have pressure or you don't and the light comes on.
I still think you have a meter problem. Could be corrosion inside or maybe a failed meter. IDK
