The MCT CM2236 NOx Sensor is a direct-fit replacement for Cummins ISB 6.7L engines (2010–2017), engineered to deliver accurate exhaust NOx measurement and stable feedback to the ECU for precise SCR dosing. Built with OE-grade materials to endure high heat, vibration, and exhaust contaminants, this assembly helps maintain emissions compliance, fuel economy, and fleet uptime.

Key Advantages

• Accurate, real-time NOx data supports optimal DEF dosing and aftertreatment control.
• Durable construction resists thermal cycling, corrosion, and soot contamination.
• Direct-fit design reduces install time and gets vehicles back in service faster.

Compatibility

• Engine: Cummins ISB 6.7L (2010–2017)

Cross-References

• Cummins: 2872236, 2894944, 2894944RX, 0435023
• Continental: 5WK96691A, 5WK9 6691A

What’s Included

• Pre-wired NOx sensor and control module assembly

Performance Insight

Accurate NOx sensing enables the ECU to keep the SCR system in the ideal operating window, helping avoid excessive DEF consumption and minimizing unnecessary regens—supporting lower operating costs and consistent vehicle performance.

Installation Notes

• Confirm the correct sensor for your application by OEM part number/VIN before installation.
• Follow OEM torque specs and routing to protect the harness from heat and abrasion.
• After installation, perform any required OEM service routines (e.g., NOx sensor learned-value reset or SCR efficiency checks) to ensure proper system operation.
