The Cummins diesel allows a percentage of spent crankcase gases back into the air intake prior to the turbocharger.  These Cummins engines employ a closed crankcase ventilation system to reduce emissions further. The Cummins 6.7L Cummins and ISX Cummins engines incorporate the Cummins Exhaust Gas Pressure Sensor, which is a Differential Sensor measuring the pressure difference between gas in the intake and the outlet of the Particulate Filter. This Cummins Pressure Sensor\u003cspan\u003e is responsible for providing the ECM with the exhaust pressure values in order to maintain the proper rates of regenerative gases into the intake stream. The Exhaust Gas Sensor is another part of the complex pollution control systems integrated into today's Diesel engines, which are used to reduce harmful emissions.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eCummins 5491909 OEM Pressure Sensor – Engine‑Ready, Plug‑and‑Play Reliability Maintains proper engine performance with the Cummins 5491909 OEM Pressure Sensor, engineered specifically for 6.7L Cummins platforms.
