02 sensor help p0158
 
Hello everyone

I'm looking for some help here, and I'm sure this is posted somewhere on here but having a hard time finding it.I just bought my first jeep its an 06 wrangler x.The check engine light came on and i had followed the key sequence to display the OBD code p0158. I'm sure its a common issue but not sure how i should go about fixing it. Replacing the 02 sensor or is it the fuse/wiring.Any help is appreciated

Thanks

Probably just needs replaced.

P0158 02 Sensor Circuit High Voltage (Bank 2 Sensor 2)

My first two quetions would be...

Have you done any offroading in water?

How many miles do you have on the Jeep?

It has 75 k on it and has been off roading by previous owner so I would assume yes

p0158
 
I've had a couple of codes on my 2002 wrangler with the most resent being p0158. This code and the last(can remember which one) I was able to fix by just looking at the hoses by the air/whatever devices and each time found one that was split. The p0158 was a L shaped hose and I taped it and the error was gone in a few runs.
So, I always would start with looking for cracked and split rubber.

Replace all O2's, use only oem/ntk/ngk, remove negative battery terminal for ten minutes. If you are having issues with one I guarantee you will have issues with more soon.

Problem solved- The prick that sold me the the jeep cleared the codes before I bought it. Took it to the spealership and this is what was found.
1 bad 02 sensor bank 2/2, 2 bad cats-covered under the federal emissions warranty, evap line had a hole in it on top of the tank.
