I have a 2013 JKU w/ 10,800 miles. Ck engine lite on and code read was PO520 Oil sensor or PSI / could be pump Dealer says . Has anyone had this Problem.

 

take it to the dealership right away, pump could be about to fail or could be as simple as a bad sensor. its under warranty so drop it off and pick it up when its ready.

 

Thanks it is at the Dealer since Monday in the AM , will let you know what was Done.

 

Me and two other buddies just had this same issue. Mine was about a month ago. Dealer had to replace the oil pressure sensor. The dealer stated they have had to do quite a few lately apparently there was a bad batch of sensors.

 

Some people have reported this or a similar code after changing to a heavier oil.
It went away after going back to the proper viscosity.
It had caused the oil pressure to be different from what the computer expected to see. (With the 3.6L Pentastar, there are 4 different expected pressures at certain rpm ranges and oil temperatures.)

 

Also be sure you've used the correct oil filter. The '14 is different than the '13 and will kick on the chk eng light and do all kinds of funky chit with the oil pump, rev limiter and oil pressure light.

The tech at the dealer said lots of folks run various viscosity oils and synthetics, etc... without issue on the pentastar.
