Ok, it's been a minute since I've been on here but I have a head scratcher. The other day I noticed my CEL had come on. I pulled the trouble code an it's a P0134 (O2 Sensor Circuit No Activity Detected). So I bought two new sensors (figured I'd replace both) and put them in. But I'm still getting the same code! I checked the wiring as far as I could and didn't find anything wrong. What the hell could it be?
