Cummins 4921505
Your 5.9L Cummins Turbo diesel engine uses a manifold absolute pressure (MAP) sensor to determine changes in the intake air stream. 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 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 MAP sensor's location on your 5.9L Cummins intake manifold near cylinder number 5.
Features of the Cummins 4921505 Manifold Absolute Pressure Sensor:
NOTE: Before you replace the MAP sensor, check all of the connections and grounds first to see that they are good and clean. Engine Sensors are electrical components, and they are Non-returnable items.
NOTE: The installation of this Cummins 4921505 on a 2002 Dodge Ram truck with the 5.9L Cummins requires you to purchase the Cummins 3104228 MAP Sensor Wiring Harness for a 2002 Dodge Cummins 5.9L diesel.
What are the benefits obtained by purchasing an OEM Cummins part?
Diesel engines use the MAP sensor as an aid to control fuel injection precisely for the best engine performance possible based on the current conditions. The MAP sensor or Manifold Absolute Pressure Sensor continuously monitors the air intake system pressure readings and then transmits this data to the ECU. The manifold absolute pressure sensor transmits data that is used to calculate: Air density, Mass Air Flow Rate, Optimum combustion performance, and or Advanced or Retarding Injection Timing.
