What does this Cummins 5491909 Pressure Sensor Do?

With the release of the new Cummins diesel engine in 2007 to meet the stricter diesel emission standards, the use of a regenerative emissions process was introduced. 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 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.

Cummins 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. This genuine replacement sensor restores accurate pressure monitoring and ensures your ECM receives the correct data to regulate engine operation, protect vital components, and prevent false warning codes.

Designed for direct OEM fitment, the 5491909 sensor connects cleanly to the factory harness for a true plug‑and‑play installation—no splicing, no modification, no compatibility issues. Whether you’re replacing a failed crankcase pressure sensor or correcting erratic exhaust back‑pressure readings, this Cummins‑built component delivers the precision your diesel engine depends on.

Symptoms of a Faulty Cummins Exhaust Gas Pressure Sensor:

• Error Code P0471 exhaust pressure sensor,
• Error Code P007D exhaust pressure sensor,
• Unnecessary filter generations.
• The power output level decreases if the sensor does not detect the filter saturation level.
• Illumination of the dashboard light for the Particulate filter.
• Reduction of filter lifespan due to unnecessary regeneration.
• Increase in oil consumption.
• Increase in pollution levels.
