Overview
The MCT CM6869 is an inlet (upstream) NOx sensor engineered for Cummins Euro VI ISB/QSB 6.7L engines. Positioned ahead of the SCR catalyst, it delivers real-time engine-out NOx data to the ECU, enabling precise DEF dosing and stable aftertreatment performance. Consistent NOx feedback supports fuel economy, reduces the likelihood of unnecessary regeneration events, and helps avoid derate conditions tied to emissions faults.
Built for the heat and vibration found in exhaust environments, this sensor is a dependable choice for fleets seeking a direct replacement aligned to the referenced OE standard. Accurate monitoring helps identify emerging aftertreatment issues sooner, supporting planned service intervals and minimizing unplanned downtime.
Compatibility & Interchange
Application: Cummins ISB 6.7L / QSB 6.7L (Euro VI), inlet/upstream position. Interchanges include Cummins 4326869 and 4326869RX, as well as 2872947 and 2872947NX. Aftermarket cross references include Dorman 904-6006, Automann 577.90547, and Dinex 5EL013. Use these references to confirm fit within your fleet’s build spec and position the sensor correctly on the engine-out side of the aftertreatment system.
