02 sensor high voltage?
 

I have an OBD2 B16a2 in a 97 CX with EX wirring harness, (katman)OBD2a-OBD2B jumper harness and a 99-00 Si ECU
I have gotten rid of all the codes except for an o2 sensor high voltage code
I waswondering fi anyone has run into this problem?
and what did you do to fix it?
I think I read at one time to put a 10ohlm resister in the power (blk/yell) wire and it should restrict the voltage and run fine? this seems logical and all but I just want to make sure
thanks
