Schaeffler NOx Sensors

Schaeffler Group supplies OE-caliber NOx sensors engineered for precise emissions control in late-model Ford Power Stroke, GM Duramax, and Ram Cummins diesel pickups, leveraging Vitesco Technologies’ OE NOx sensor lineage within Schaeffler’s Automotive Technologies and Vehicle Lifetime Solutions aftermarket program.​

OEM quality

  • Built to OE specifications for accuracy, stability, and durability, Schaeffler NOx sensors support upstream and downstream SCR control in Ford, GM, and Ram diesel platforms to meet regional emissions standards.​

  • The portfolio reflects Vitesco’s OE sensor heritage now offered through Schaeffler’s aftermarket channels, delivering direct-fit replacements that maintain factory performance characteristics.

Certifications

  • Schaeffler operates global, audited quality systems with automotive-grade certifications and documented product safety processes that govern design, production, and validation.​

  • Certificates and environmental statements are published via corporate and regional portals, reflecting a continuous-improvement culture across manufacturing sites.

  • High-precision NOx and O2 measurement with rapid response stabilizes SCR dosing and reduces DTCs, DOC/SCR stress, and regeneration issues—supporting low in-service failure rates in high-mileage diesel use.​

  • Standardized product safety and quality management help minimize complaint rates and field failures, reinforcing long-term reliability for work trucks and towing applications.

Ford Power Stroke applications

  • Upstream sensor: measures engine-out NOx for accurate DEF dosing on 6.7L Power Stroke platforms; downstream sensor: verifies SCR efficiency and catalyst health for emission compliance.​

  • Schaeffler’s Vitesco-derived sensors are engineered for OE-style mounting positions, harness interfaces, and ECU strategies used in Ford’s SCR systems across multiple model years.

GM Duramax applications

  • Supports LML, L5P, and related Duramax platforms with upstream/downstream roles in DEF dosing control and SCR performance verification to maintain factory emission targets.​

  • OE-derived signal stability and thermal robustness align with GM exhaust layouts, enabling precise closed-loop control and fewer nuisance DTCs under heavy load and towing.

Ram Cummins applications

  • Designed for 6.7L Cummins SCR systems with an upstream sensor for dosing calculation and a downstream sensor to validate catalyst conversion efficiency and trigger corrective strategies if needed.​

  • Schaeffler’s OE-grade components match Ram’s harnessing and sensor placement conventions, supporting reliable performance in commercial-duty and high-idle service.

Emissions performance

  • Typical diesel layouts use upstream NOx for DEF control and downstream NOx for catalyst monitoring, ensuring compliance with stringent standards like Stage V and equivalent North American limits.​

  • Signal accuracy and stability help optimize DEF and fuel usage while maintaining real-world emissions compliance in varied duty cycles.

OEM sources and lineage

  • Offered through Schaeffler Vehicle Lifetime Solutions and REPXPERT, these sensors trace to Vitesco OE platforms widely adopted by vehicle manufacturers, ensuring OE-level fit, form, and function.​

  • Catalog references confirm Schaeffler/Vitesco NOx sensor part families used in OE and direct-replacement aftermarket programs.

Global manufacturing and support

  • Schaeffler’s regionalized production footprint and sensor expertise enable consistent quality and dependable supply for professional service operations.​

  • Vehicle Lifetime Solutions provides OE-quality parts with technical support and repair guidance tailored for diesel service bays.
