code 41
Hey all.
I have a 1994 Civic EX Coupe. The previous owner has had the car for years and then left it sitting for about 5 months before selling it to me. When I got it it had the check engine light on.
I checked the code and it was 41 which was the primary O2 sensor heater circuit. I searched here and found some people changing the O2 sensor to fix it so I did the same. However, the code persists. I even reset the ECU after the O2 sensor install.
Any other ideas? I see no O2 heater relay or fuse...
Oh yeah, and I used a Denso plug and play O2 sensor.
