Your Cummins Turbo diesel engine uses an Air Intake Temperature Sensor pressure 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 engine 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 Air Intake Temperature or Temperature Sending Unit Sensor.
