Impossible Code 1 HO2S Problem.
Here's what im working with:
'90 CB7 (Accord)
JDM H22A
JDM P13
So i have a very persistent issue that ive done hours and hours of research for. I cant seem to find a solution. Im pulling a code 1 which is HO2S of course, but heres the problem; Ive replaced my O2 sensor twice (both Denso) and ive checked each sensor wire for a short or to make sure its a complete circuit from the sensor to the ECU harness. So ive rulled out it being a faulty sensor and/or wiring. But, heres one slightly important tip; I can run my car off of my P14 ECU perfectly fine. No CEL and runs great, but no VTEC. I thought there was a possibility of it being a faulty ECU, so i took it apart and inspected it and found nothing out of the ordinary. And to be sure i tried a different JDM P13 and got the exact same result. Not sure where else to look now. Any ideas???
