Cummins 3408345
Your Cummins Turbo diesel engine uses an Intake Air Temperature 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.
NOTE: Before you replace the IAT sensor, check all of the connections and grounds first to see that are good and clean. This is an OEM Cummins replacement part that is a NON RETURNABLE part.
