 Engine Oil Pressure Switch Circuit
|
Circuit Description
The engine oil pressure sensor is used by the electronic control module (ECM) to monitor the lubricating oil pressure. If the oil pressure drops below the engine protection limit, the switch will close and cause Fault Code 415 to log. When the engine is not running, the oil pressure switch will be closed. The oil pressure switch will open when oil pressure is above 48 kPa [7 psi].
Component Location
The oil pressure sensor is located on the intake side of the engine on the engine block, below the fuel filter.Refer to Procedure 100-002 (Engine Diagrams) in Section E for a detailed component location view.
