Discussion:
Vehicles have been showing up at dealers with engine runs rough and/or Diagnostic Trouble Code P06DD set. Dealer during normal diagnosis could also identify that the oil pressure is low.

Beside the normal diagnostic procedure possible causes the two items below should be verified:

1. One cause of this has been determined to be that the wrong oil filter has been installed after an oil change by an independent repair facility or the customer that has purchased the oil filter in the aftermarket. These filters may be too short or even slightly too wide.
If this is present, firts verify that the correct mopar oil filter has been installed. This can be done by verifying the part number on the filter or that the filter has the Mopar symbol on it. if the incorrect filter is installed correct this condition and inform the customer that they should return to the point of purchase for a refund.

The correct Mopar part number is 68079744AB

2. The second cause has been determined to be a cut or slit in the O-ring at the top of the pick-up tube on the oil pump. A bore scope can be used to view the top of the pick-up tube to see if the O-ring is not seated all the way around the tube. The O-ring is blue in color and it should not be visible if installed properly.
