O2 sensor still not working?
hey all,
I've been driving around for a few months with the CEL on. I first noticed it in October or so, and I pulled the codes... 0303 and 0503, right and left O2 sensors. I figured this meant the sensors were shot, so I just replaced them over my x-mas break. I left the battery disconnected for a few hours to reset the ECU, and I reset the CEL. After I finished the install, the light is still on!! I pulled the codes again, and they're still 0303 and 0503. I tried reseting the light like 5 more times, still nothing. What's going on here? Please help!
