2008 Jeep Wrangler unlimited Sahara- Check Engine light P0157
 

Hey folks looking for some help. I know the wrangler has 4 O2 sensors, I just don't know which one the bank 2 sensor 2 is. A picture would be great if anyone has one. The Jeep only has 75000 kms on it and I suspect its the O2 sensor since the code P0157 refers to it. If anyone has had this issue before please share. Thanks for your time.

Might be just a slightly dirty connection, try disconnecting it and re-connecting it a few times to clean it up. Then clear the code and see what happens. It should be the one after the cat on the drivers side.

Thanks for the reply, I was driving it and the light went off by itself. So far so good the CE light hasn't been triggered yet .

Sounds familiar I use a small piece of black electrical tape when it comes on and when its off so is the tape.. You might have one of the extended warrantee plans on that vehicle which might cover this?

Yes it is covered . 8 years or 130000 km

Bank 2 is the left bank of the engine (drivers side). There will be 2 oxygen sensors on this side. The sensor located before the catalytic converter is bank2 sensor1. The sensor located after the cat would be the one to change, bank 2 sensor 2. (the most rearward sensor on the drivers side)
