Quick Ship SKU #: CMNS-3971106 Cummins 3971106 Manifold Air Pressure (MAP) Sensor 03-07 Dodge 5.9L Cummins

The MAP sensor on your Cummins is responsible for telling the ECM the density of air getting to the cylinders. If this sensor is reading incorrectly, the ECM will not be able to accurately tell the injectors how and when to fire, causing poor engine performance. This is a genuine Cummins replacement MAP sensor to get you back on the road reliably.
