DODGE RAM Cummins 5.9-6.7L Engine Nox Sensor - Inlet

How NOx Sensors Impact Engine Performance

At Midwest Heavy Duty, our advanced NOx sensor technology is engineered to help your engines perform better by accurately monitoring emissions and ensuring optimal operation of your aftertreatment system.

With reliable NOx readings, your engine can maintain peak efficiency, improve fuel economy, and reduce costly downtime caused by emissions-related faults.

Our sensors help maximize engine uptime by supporting precise control of the Selective Catalytic Reduction (SCR) system, leading to more effective reduction of harmful nitrogen oxides (NOx) — while protecting your engine’s long-term health.

How to Maximize Emissions System Performance

Midwest Heavy Duty helps you maximize your emissions system efficiency and minimize maintenance costs through three critical advantages:

• Superior Sensor Accuracy:

  Our NOx sensors deliver precise and real-time feedback to the engine control unit (ECU), allowing the SCR system to make exact adjustments. This reduces the risk of excessive DEF consumption and minimizes active regeneration cycles, which helps maintain better fuel economy.

• OEM-Grade Durability:

  Built to meet or exceed original equipment standards, Midwest Heavy Duty NOx sensors are rigorously tested for long-term durability. Withstanding extreme temperatures, vibration, and contamination ensures reliable readings over the sensor’s full life.

• Faster Diagnostic Capability:

  Accurate NOx monitoring allows the ECU to detect issues earlier, often before they trigger a fault code or cause engine derating. By identifying potential problems sooner, you can avoid costly repairs and maximize vehicle uptime.
