Is your 2003-2007 5.9L Cummins feeling sluggish, delivering less power, or experiencing rough idling? The culprit might be a malfunctioning Manifold Absolute Pressure (MAP) sensor. This vital component in your 3rd Gen Dodge diesel precisely measures the boost pressure within your intake manifold. This reading is then relayed to your engine's computer, which critically adjusts the fuel delivery for optimal combustion. When this sensor fails, your engine operates with an incorrect air/fuel ratio, leading to a noticeable decline in performance and drivability. Restore your truck's lost power and efficiency with the Cummins 3971106 MAP Sensor, a direct-fit replacement engineered to bring your 5.9L Cummins back to its peak.
