Wrangler JKU 2008 - All O2 sensors disconnected, still codes p0031 p0037 p0051 p0057
Hi!
I've got all the codes mentioned in the title. Tried disconnecting the sensors one by one to see if there was one faulty making the other ones fail. But now, all is disconnected and I still get these codes. Just these codes, nothing else.
Anyone have any idea of what it could be? Checked all grounds and everything is fine.
