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 & 3500 5.9L Cummins Turbo Diesels Tier 3 Marine 5.9 liter QSB engines. Tier 3 Marine 5.9 liter ISB engines. 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 Pressure Temperature 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. It ensures the engine remains at its optimum performance level and receives the ideal air and fuel supply. These pressure changes indicate engine load, boost, operational elevation, and othe
