Direct Replacement for Cummins 2872297
The MCT CM2297 is a NOx sensor designed for heavy-duty exhaust aftertreatment systems, serving as a replacement for Cummins part number 2872297. Installed within the exhaust stream, it provides real-time nitrogen oxides data to the engine control unit, enabling proper SCR dosing and stable emissions performance. Cataloged alongside other Cummins-focused NOx sensors, the CM2297 follows MCT’s direct-fit replacement approach for streamlined service. For best results, verify compatibility by matching the OE number on the original unit.
Built for Reliability in Heavy-Duty Exhaust Systems
Constructed for harsh operating environments, the CM2297 maintains signal integrity under heat, vibration, and contamination typical of on‑highway and vocational duty cycles. Consistent NOx feedback helps the ECU maintain efficient aftertreatment operation, supporting uptime by reducing emissions-related faults and limiting unnecessary troubleshooting. The sensor is specified for use in exhaust applications where durable, OEM-style connections and stable performance are required.
Fitment and Cross-References
Use Cummins 2872297 as the primary reference for fitment. Cross references include Dinex 577.90536, Dorman 5293295, and other listings such as 5EL003 and 2872277. When servicing mixed fleets, confirm the OE on the removed component to ensure a precise match.
