bank2 sensor2

What does this (bank 2 sensor 2) mean? I have that code (p0158) and I'm trying to figure out which sensor needs to be switched out. Any help would be would greatly appreciated.

Re: bank2sensor2

Simply means that your o2 sensor after the precat on the passenger side is throwing a fault code. Here's a diagram of sensors for 4.7 > http://www.wjjeeps.com/oxygen_47.jpg and a list of fault codes > http://www.wjjeeps.com/faultcodes.htm#0100

Re: bank2sensor2

The upstream sensors 1-1 and 2-1 (upstream seen from the precats) are used for finetuning the fuel/air mixture when in closed loop mode, while downstream sensors 1-2 and 2-2 are used to measure the effectivity of the catalitic converter.
The sensors from the stealer are quite expensive, but they are made by Denso, so you could choose to just get the same Denso P/N as the one you want to change.
Don't use Bosch sensors. Eventhough they make good sensors, the heating of those sensors is too slow for our jeep PCM program and they will trow you an other fault code.
Be aware that the upstream and downstream sensors are not the same.

Re: bank2sensor2

If you go to rockauto.com and read the descriptions carefully on the denso sensors you can find the right one no problem. They are pretty easy to replace especially if you have an o2 sensor socket, but that isn't necessary. That code seems to indicate a faulty sensor, but since it is downstream and not used for fuel trims like Frank said, there is no absolute rush to replace it, other than to get the MIL to go away.
