Manufactured by \u003cstrong\u003eSensata\u003c\/strong\u003e and built to OE signal specification, it measures the pressure drop across the diesel particulate filter on the \u003cstrong\u003eVolvo D13\u003c\/strong\u003e engine so the engine control module knows how loaded that filter really is. When this sensor drifts or dies you get dash warnings, stored fault codes and derates — often on a truck whose filter is in perfectly good shape. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.\u003c\/p\u003e\n\n\u003ch2\u003eHonest Regens: The OE Differential Pressure Sensor Advantage\u003c\/h2\u003e\n\n\u003cp\u003eThe differential pressure sensor is the input the engine control module leans on to decide whether the particulate filter needs a regeneration. This \u003cstrong\u003eSensata\u003c\/strong\u003e unit carries a \u003cstrong\u003e35 kPa\u003c\/strong\u003e rating and is manufactured to OE signal specification, so the module sees the signal it expects from the factory part rather than a close-enough approximation from a generic substitute.\u003c\/p\u003e\n\n\u003cp\u003eGetting that one input right is worth real money. A sensor reading high commands regens the filter never needed, which burns fuel and puts needless heat through the aftertreatment; a sensor reading low lets soot pack the filter until the only way out is a forced regen or a filter cleaning. Either way the fix is the same sensor. Verify the fault with diagnostics before you replace it, though — plugged or cracked pressure lines running to the filter will set the same codes, and a new sensor will not fix a line.\u003c\/p\u003e\n\n\u003cp\u003eAt FleetPro Parts \u0026amp; Tires, we stock the OE-grade part instead of the cheapest one on the shelf.
