HELP please, O2 sensors not reading, got a CEL.
So these are the codes I currently have:
P0030: H02S Heater Control Circuit Bank 1 Sensor 1 P0050: H02S Heater Control Circuit Bank 2 Sensor 1 P0135: H02S Heater Performance Bank 1 Sensor 1 P0155:H02S Heater Performance Bank 2 Sensor 1 P0443 Evaporative emission Purge Selenoid Control Circuit My O2 fuse keeps blowing, I've looked at all the O2 wires under my hood and by my cats and could not find one that was melted or burned causing a short. Can not figure out why both front O2 arent working, any ideas please???

I had my driver's side precat O2 sensor fail. It threw a TON of codes--actually codes for ALL the sensors (even tho I don't have rear sensors, and have the MIL disabled in the tune) and a powertrain code, too. (Can't remember exact codes, sorry)
The only way I could tell which one I needed to replace was to view the raw data in Torque. B1S1 was very slow and erratic response, while B2S1 was reading predictably. Replaced the failed one, reset the light, and no more problems. As far as your fuse blowing, sounds like a wiring problem, but it could also be a fault inside one of your sensors...albeit not very likely. More likely problem is some kind of rodent snacking on your wires. Good luck either way.

If you don't have a multimeter to test for a short.....
Unplug all of them and see if it blows a fuse... If not plug one back in at a time to see which one blows the fuse. If it blows without them plugged in... must be wiring... My guess is that one of the heated sensors is shorted out internally.
