I've been getting O2 sensor codes for almost a month now. CEL is on. Codes are: P0036, P0141 and P0054. I've had my O2 sensor replaced (twice now). AC Delco is in there right now (bank 1 sensor 2). I took it to a shop and they said there's no battery voltage at the O2 sensor fuses/circuit inside the fuse box. He said the wiring "visually looks fine" and that I need a new fuse box. Does this sound right? He said the circuit inside the fuse box is what gives power to the O2 sensor wiring. The battery had the normal 12 volts. I just want to make sure this is even possible since I've already put about $1,000 in my car within the last month. I just don't want to get a new fuse box put in for $300 more and find out it was something else.
have the same problem?
