Need more info. Simply put, the code indicates a problem with the heated O2 sensor. Is it wired properly? Is there an open in any of the wiring? Did you test for continuity? Can you replace the current sensor with a known good one to see if the problem goes away?
I'm also just curious, how did you adapt the HF cable clutch for the hydro clutch d15z1 (VX) engine? Did you replace the gauge cluster too (the HF speedo is cable driven and the VX is the electrical signal kind of sensor). And I have been told on what seemed like pretty good professional authority that the HF and fourth gen Civics had a shorter countershaft than the 5th and 6th gen and therefore cannot be swapped... your case suggests maybe that's not true.
