My daughter has a 16 JK. Went trail riding or should I say she got it stuck in mud. CPS code Bank 2 Sensor 2. It had all the symptons. But the other issue now is that when you first crank it up it sounds like a diesel.(rattle). The oil light also stays on. At 700 rpm its on above 700 rpm it goes off. Checked oil level right where its supposed to be. No oil leaks found. Cked pressure while idling its at 85. So what to do now and what sensor would be bad now? And hopefully the rattle is not the engine failing. 69,000 miles.
