2003 to 2006 Dodge Ram 5.9L Cummins Oil Pressure Sensor
Your Cummins 5.9L turbo diesel engine uses a pressure sensor to determine the engine's oil pressure. The engine oil pump generates the oil pressure, and the oil pressure sensor is used to monitor the performance of the engine oil pump. Engine oil pressure is critical for safe and prolonged engine operation.
If you are having problems with the cold engine starts with your Dodge Ram, it could be the oil pressure sensor. The engine will not be able to start if the oil pressure sensor has failed.The pressure changes are used to indicate engine load, boost, operational elevation, and other pressure variables that enable your ECU to make necessary changes so your diesel can run at peak performance.
