I have a 2011 1500 4.7L that has a constant CEL on. A little back story... just over a year ago I had a Magnaflow 22" cat back system put on and I added a k&n intake as well. I drove from NC to ND just in time for the snow. Last winter the CEL would come on and go off intermittently but since about the middle of summer it's been on constantly. I've read the codes numerous times and it's showing all banks/all sensors are bad. That seems odd to me. Can anyone help me out with this? Is there something that would cause this? Im sure there is other posts about this so if you guys have links to them, thanks in advance. Any help would be greatly appreciated as it's getting cold and the remote start is disabled with an active CEL.
