Dodge Ram 5.9L Cummins Boost Pressure Sensor - Manifold Absolute Pressure Sensor 


The Cummins 3971106 Replacement MAP Sensor applications:

  • 2003 to 2007 Dodge Ram 2500 5.9L Cummins Turbo Diesels
  • 2003 to 2007 Dodge Ram 3500 5.9L Cummins Turbo Diesels

The Boost Sensor for the Cummins 3971106 5.9L Cummins diesel engines is also known as:

  • Boost Pressure Sensor
  • BPS
  • Manifold Absolute Pressure Sensor
  • MAP Sensor

Your 5.9L Cummins Turbo diesel engine uses a boost sensor / manifold absolute pressure (MAP) sensor to determine changes in the intake air stream. The boost pressure sensor in a turbocharged engine determines the air pressure in the intake manifold. The Boost Pressure Sensor monitors the speed and airflow pressure in the intake manifold and ensures that the engine remains at its optimum performance level and is receiving the ideal air and fuel supply. These 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. If your Dodge Ram 24 Valve ISBE Cummins Turbo Diesel truck is experiencing decreased engine performance, it could be the MAP sensor. This is an OEM Cummins Sensor with an oval wiring harness connector. The Boost sensor is located in your 5.9L Cummins intake manifold near cylinder number 5.
