<h4>Overview</h4><p>This is a diesel engine sensor for the Ram, Dodge 5.9L Cummins 12V diesel (1998-1998). Built to OEM specification and engineered as a direct-fit replacement for a professional-grade 5.9L Cummins 12V repair or service. Every order ships fast and is backed by our support team.</p><h4>What It Does &amp; How It Helps</h4><p>Engine sensors are how the ECM sees what the engine is doing — pressure, temperature, position or flow — and it trims fuel, timing and boost from their signals. When a sensor drifts or fails you get a check-engine light, hard starting, poor power, smoke, or a drop into limp mode. A direct-fit replacement built to OE performance restores an accurate signal so the ECM can control the engine correctly again, clearing the fault at its source instead of masking it.</p><h4>What's Included</h4><ul><li>a direct-fit replacement diesel sensor built to OE performance</li></ul><h4>Fitment</h4><p>Fits Ram, Dodge trucks equipped with the 5.9L Cummins 12V diesel engine, 1998-1998.
