thats the same problem I ran into with my hx that i did a y8 swap in using the same harness I ended up swapping harness with the y8 harness and it ran great with the p2p ecu then... but to answer your question yes thats the reason being a 5 wire o2 for the y5 harness and the p2p doesn't like that

You'll need to run the wiring for the knock sensor to the ECU as well.
