Heater Control Circuit Code

So if this has already been covered I apologize but I just pulled out of my drive way and my JK steering felt stiff like when the engine cuts out but it didnt, check engine came on so i drove her back home and got this code on my OBD2: P0058 (Bank 2, Sensor 2) where can I locate this and is bank 2 / sensor 2 rear driver? Thanks in advance for the help.

Is it recommended to replace all 4 the same time even though one is throwing code? I assume gas mileage will improve and one less thing to replace later on. What have others done, also these buggers arent cheap. OEM Mopar, NGK/NTK, Bosh? pros and cons please.

You don't need to replace all the sensors. Only one that is bad.

The code you have here is for the heater element in the downstream O2 sensor of the bank 2. This should be located on the left side of the vehicle after the catalytic converter.

There is a heater circuit on the o2 sensor to heat it up as they work better when they are hot. It allows the engine to run more efficiently quicker at start up.

Odds are it's a bad sensor but you usually want to test the circuit to make sure before you throw a sensor at it and then realize it's the wiring. Usually you can take a test light and back probe the o2 sensor heater circuit. Connect the test light and it should light when you start the Jeep.

Thanks sequel. But I already bought the left down sensor went with oem NTK but man i spent an hour trying to break her free and she is seized. i used Penetrating oil, flex ratchet with a 7/8 o2 socket and a pipe extension for leverage. Tomorrow going to try a 22m ratchet wrench or a lower profile o2 socket so i can fit a bigger breaker bar for better leverage (space is tight - left down) I did remove the fender to access it better. I was really hoping this darn thing came out easy but not my story, ugh. Any other tricks with breaking free a seized sensor on left downstream?

Job done, sensor came out by using Freeze Off by CRC, sprayed it down for like 15 sec, put a 22m wrench on hit, tap tap tap the wrench with a hammer right on the nut, gave her a big tug and it broke loose. Code cleared, check engine light gone. Happy Jeep!
