05 xj8l codes p0037 p0057 p1646 p1647 O2 sensors
Hi Everyone:
I am getting the above-mentioned OBD2 codes -- all relate to the O2 sensors, I believe -- both banks, upstream and downstream.
Any thoughts as to likely cause(s)? It seems unlikely to me that all 4 would fail at one time for independent reasons, so possible explanations and/or things to check would be most appreciated.
Thanks in advance.

The first thing that comes to mind is a vacuum leak. I can't imagine all the sensors going bad at once. I'm going to hook the smoke machine up tomorrow.

Havent troubleshooted it yet,
Not burning oil, that I know of, but I'll look into it.
however I can tell you that I have gone into limp back mode one time since all faults where there. Other than the one time, no other major issue.
I need to get the jag lifted, so that I can swap out all 4 o2 sensors.
do you know where the short was?
thx

Thank you for the update, do you have any idea what part of the loom is the trouble spot. I'll start checking my harness. In the past I had an intermittent issue with a right bank o2 sensor so this is starting to make sense.

From the fuel pressure posts I've read it seems like my fuel pressure range is the norm, so in other words Alldatadiy.com can't be trusted. I reset the codes and put some miles on the car waiting for some fresh codes, so far all the monitors are set so no issues. At the moment with no clear problem I'm at a stand still, maybe bad gas set the code? Let me know if you guys come up with some better info.
