Default fuse for o2 sensor? 08+wrx

just seeing if there is a location in either of the 2 fuse boxes either under the drivers side dash or under the hood in that box where there is a fuse for the o2 sensor. i've read that you should check the fuse before going out and buying a new sensor

Just test all the fuses with a test light and see if one of them is blown. If the o2 sensor has 12 volts going to it for the heater or whatever then it would be fused somewhere.. but its probally on the same system as other things as well and would not have its own dedicated fuse.

Your car is a 09.. and your oxygen sensor is gone allready? Warranty should cover that..

no i dont know if my sensor is gone already...i had another thread b ut got no response. my rear o2 sensor rubbed on the drive shaft and it wore away the green cover and 2 of the wires ripped..maybe this shorted something. i keep getting codes for the front and rear o2 sensors i think they are 0031 and 0037. i can clear the rear but it comes back, the ap will not let you clear the front. my car has 12000 miles on it so i doubt my o2 sensor went even tho i know i will need a new rear since it tore. i am st 2 so i doubt the dealership would cover this under warranty. any help would be great

The O2 sensor generates its own current based on the difference in 02 concentration on both sides of the element. There is an atmospheric side and the exhaust side, there is also a heater element but it's only used when the O2 sensor is cold. Rich A/F ratios will generate current because of the difference in O2 concentration (Oxygen present in the atmosphere versus the lack of oxygen in your exhaust). I would imagine that there may be a fuse for the heater element present in the O2 sensor, but if the fuse was blown it would only affect the O2 sensor when the car is cold. the current generated by the O2 sensor itself is very small and I'm pretty sure that it isn't hooked up to a fuse, but I'm not 100%.
