Heated 02 Sensor Bank 1,Sensor 1

So this code basically means the 02 sensor in the exhaust manifold.I changed it out but check engine didnt clear.The probable cause are:

1- 02 sensor defective
2- poor connection at oxygen sensor
3- check circuit fuse

Im sure its number 3.Were is that exactly?I also noticed the fuse to the clock and side mirrors went out again after only maybe 1-2 weeks on me replacing it.I guess there is something shorting it out.

Any help is appreciated.Thanks.

damit i just found a thread that says bank 1 is actually an 02 sensor by the firewall.I guess I changed out the wrong one.I never knew there was an 02 back there.

 

haha i did the same thing today

 

Did you change it out already? Im gonna wait till the daytime to see how it is.I hope I still have the old 02 sensor I removed from the header.I guess I put in a new one for nothing.Maybe the rear one is the same as the new one?I can just reuse it.

Anyone have an idea why my mirror/clock fuse went out again?

 

i changed it out, and broke the old one by accident wile doing it

so i guess i cannot reuse it.... autozone here i come again

 

What route did you go to pull it out.Im about to go outside and look at it.Maybe I can get my gf to fit her little hand in there to get it.

 

Wow I cant find it

 

I bought a new sensor, put it in the front and found out i should have changed the back one. I got a bank 1 sensor 1. So I took the original one I took out of the front and put it in the back.

I still get the check engine light. I disconected the battery, the I took out the EFI fuse. Both times the check engine light went out. It's when i went to restart it the check engine light came back on.

Do I need to buy a new sensor for the back? The old one worked on the front.
Help?????????

 

The manual state to check the resistence of the heater (at the ecm, with the connector removed from the ecm) and then check the fuse. Before replacing the sensor.
