P0524: Engine Oil Pressure Too Low
17 vehicles · 14 makes · $50-$20,000 repair
Most Reported On
P0524 is an OBD-II diagnostic trouble code meaning “Engine Oil Pressure Too Low.” This code sets when the engine control module sees that engine oil pressure has dropped below the safe minimum threshold, based on the reading from the oil pressure sensor (or switch). Adequate oil pressure is what keeps a protective film of oil between the bearings, crankshaft, and other moving parts, so the computer treats low pressure as a serious warning. It can mean the actual pressure really is too low, or that the sensor circuit is reporting a false low value. Because true low oil pressure can quickly destroy an engine, this code should be checked immediately and the engine not run hard until the cause is confirmed. This code is most commonly reported on 2005-2008 Dodge Magnum, 2007-2009 Hyundai Entourage, and 2014-2020 Kia Cadenza, plus 14 other vehicles, with repair costs ranging from $50 to $20,000.
