Accord Euro-R CL1 o2 Sensor

[funnyvictor86]

Hey guys some of you may know me, I'm also on several other accord forums. I got a CEL P1166 (primary o2 sensor). I have a 6th gen sedan with a h22a from an Accord Euro-R (CL1). The ecu is basically pinned like an obd2b ecu but it only utilizes one o2 sensor like an obd1 equipped vehicle. My issue is do I get an o2 sensor from a H22 equipped 4th gen (92-96) Prelude or 5th gen (97-01) Prelude? Also is there any way to test an o2 sensor? Thanks.
