Dodge 5.9L Cummins Intake Air Temperature Sensor  - IAT Sensor - MAP Sensor -  Air Intake Sensor Temperature

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

  • Dodge Cummins Intake Air Temperature Sensor 
  • Air Intake Pressure Sensor

Your Cummins Turbo diesel engine uses an Intake Air Temperature Sensor manifold absolute pressure (MAP) sensor to determine changes in the intake air stream. These Intake air temperature 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 IAT sensor.
