Volvo Repair: obd2 code 1330, obd2 code, low oil pressure

Question
Could you tell me what the code 1330 means.  This 2001 S80 has the NO OIL PRESSURE light come on if the car gets hot, I have been cleaning the engine with MerconIII as well as engine flush chemicals.  Please advise!!!

Answer
Robert, Sorry, that trick isnt going to work.  You need an oil pan reseal kit.  The pickup tube oring and pan oring is usually the culprit.  I would also do an oil pressure test.  We have seen low oil pressure problems in these engines.  Sometimes the oil pans reseal does the trick.  Other times the main bearings are too shot.  Either a rebuild is in order or a low milage engine swap is the remedy.  The 1330 code means nothing.  Its not even listed in the list of PO codes.  Hope this helped.
