Cummins X15, X12 Differential Pressure Sensor 2018-2024: OEM 5492073

Reliable Differential Pressure Monitoring for Cummins X15 & X12 Engines (2018–2024)

What is it?
The Cummins X15, X12 Differential Pressure Sensor with OEM part number 5492073 is a critical emissions-related sensor used on Cummins X15 and X12 diesel engines built from 2018 through 2024. This sensor measures the difference in pressure across the Diesel Particulate Filter (DPF), providing real-time data that helps the engine control system determine the condition of the particulate filter and manage regeneration.

Why choose this Differential Pressure Sensor?
This sensor is manufactured to Cummins’ original specifications, ensuring accurate readings and seamless integration with the vehicle’s aftertreatment monitoring systems. When the differential pressure sensor becomes weak or fails, the engine control module (ECM) may receive incorrect data about the DPF’s condition, which can lead to unnecessary regen cycles, warning lights, reduced engine responsiveness, or misreported backpressure. Installing the correct OEM-specified sensor helps maintain precise pressure readings and supports balanced emissions performance.

Key Benefits
✅ Designed specifically for Cummins X15 and X12 engines (2018–2024)
✅ Provides accurate DPF pressure differential data to the ECM
✅ Helps support efficient DPF regeneration logic
✅ Direct replacement — no modifications required
✅ Built for harsh exhaust environments and extended use

Applications
This differential pressure sensor is suitable for medium- and heavy-duty trucks and commercial vehicles equipped with Cummins X15 or X12 engines manufactured between 2018 and 2024. It’s commonly found in long-haul tractors, regional transport rigs, vocational trucks, and other commercial applications where precise emissions monitoring and particulate filter management are essential.

Installation Notes
Before servicing, ensure the exhaust and aftertreatment system has fully cooled. Locate the differential pressure sensor on the DPF or related piping, disconnect the electrical connector, and remove the old sensor. Inspect the sensor mounting port and wiring harness for contamination or damage before installing the new unit. Thread in the replacement sensor and secure it to the correct torque specification. Reconnect the electrical harness, clear any stored fault codes, and verify proper pressure monitoring using diagnostic tools.

Final Thoughts
If your Cummins-equipped vehicle is displaying DPF backpressure warnings, unusual regeneration behavior, or inconsistent emissions data, replacing a faulty differential pressure sensor with the correct OEM unit can help restore accurate monitoring and smoother aftertreatment function. The Cummins X15, X12 Differential Pressure Sensor (OEM 5492073) plays a pivotal role in managing emissions system feedback and supporting dependable vehicle operation.
