OMP help
 

Hey all, Im having OMP troubles again. Im getting code 27 so I'm going through the FSM troubleshooting steps, but have come across a little snag. The FSM states there should be continuity from 4I, 4J, 4K, and 4K to S1-4 respectively, but I get continuity from 4I and 4J to B1 and B2. The OMP resistances check out and are 25ohms where they should be, but I think there is some kind of issue with the wiring somewhere, but that leads to a new problem being that the Emissions harness is almost brand new, less than 2500 miles since it was installed, so I really hope that its the problem, but considering I am somehow getting crossed signals I am looking for any other ideas that people may have.

Thanks for the help.
