Code P0523 Dodge Description

The P0523 diagnostic trouble code (DTC) for Dodge vehicles indicates a problem with the engine oil pressure switch circuit being too high. This switch is responsible for monitoring the oil pressure in the engine and sending a signal to the engine control module (ECM) when the pressure is out of the specified range. When the ECM detects that the oil pressure switch circuit is reading higher than it should be, it triggers the P0523 code.
