I have a 93 civic cx with a mini-me swap in it and ever since i did the swap i cant shake the o2 code. the first swap i did on this car was a jdm d15b vtec with the jdm d15b po8 ecu which requires a single wire o2, so i converted from the 4 wire to the single wire when i did that swap about 8 months ago, and it ran perfect, about a month ago i built a mini me and swaped it in didnt even mess with the wires simply dissconnected them and swaped the motor, and the code appeared and would not go away, this damn thing.
the first thing i did was re- check my wiring, and when i did that i noticed that the vtec wire and the o2 wire had shorted out together, so then i completely re ran the wires and double checked them with the ohm meter.
i figured since the o2 runs off of such small voltage crossing over with the vtecs 12 volts probobly fried it- so i went and bought a brand new boshe one from autozone pluged it in and still throwing an o2 code- damn the o2 all to hell
these are my thoughts i know the wiring and the o2 are completly fine, so im thinking maybe i fried something in the ecu or maybe the mini-me itself is causing the o2 code, but i thought if i was throwing an o2 code it means "faulty wiring or faulty sensor" ? im lost?? any thoughts?
