My son's 2012 JK has gone crazy the past couple of weeks. I am getting the same codes. I just replaced the oil pump, oil cooler assembly, all the coil packs, and plugs.
He drove it to school yesterday and it would not shift out of first gear. He ran it at high RPM's until the oil light came on. Now the engine has a rattle when it gets above 2k RPM.
I am going to try and get the gremlins out before tearing the engine down.
I am starting this weekend by changing the ABS sensors on the wheels.
I am going to order the oil temp/pressure & knock sensor harness and get it replaced.
Hopefully that will get the gremlins out.
Then I will start with the rattling sound.
Probably the rod bearings.
