This Mopar 68282012AA MAP Sensor for the 2007.5 to 2019 versions of the Dodge Ram trucks with the 6.7L Cummins diesel engines. The Cummins 6.7L diesel uses this sensor to measure the Absolute Pressure of the incoming air. This Sensor is one of the two different engine sensors located on the 6.7lL Cummins inlet air system. Please make sure this is the correct sensor you need before ordering. Engine Sensors are an electrical component, and they are a NonReturnable item.
Your 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 6.7L Cummins Turbo Diesel truck is experiencing decreased engine performance, it could be the MAP sensor.
NOTE: Before you replace the MAP sensor, check the all of the connections and grounds first to see that are good and clean. This OEM Mopar Engine Sensors are an electrical component, and they are a NonReturnable item. The 6.7L Cummins diesel engine also uses an IAT Intake Air Temperature Sensor for proper engine operation. Please make sure you are ordering the correct sensor for the trouble code you are trying to fix.
