Last week I talked with the people at Hondata and found out that the cause of my check-engine light and the AFR failure is that my O2 sensor doesn’t match my ECU. They said I needed to buy the primary O2 sensor out of a base-model RSX (or 2004 Civic Si). So I did, and last night I wired it in. Still no AFR, and still the P1166 CEL.
The worst part is that I dished out a lot of money, and I can’t return the part. I know there’s something wrong with the wiring, but apparently I’m not smart enough to figure it out.
