Re: Jdm o2 sensor replacement
the ECU tells you what it uses. If it's a JDM ECU, you only have a primary O2.
it will also be a different code for primary(pre-cat) vs secondary(post-cat).
how do you know that you have a code for the O2? (which code is it?)

Re: obd2 JDM LS throwing o2 sensor CEL code
replace pre-cat O2 since you only have one O2.
high voltage on IAT, make sure you didn't swap the IAT and EVAP purge solinoid plugs.

Where did you put the IAT (I'm assuming you have 96-00 Civic which has the IAT in the airbox or intake arm) or did you wire up a round style plug?
