Fitment (Market-Validated Usage)

Based on Ford OE catalog references, aftermarket cross-reference listings, and supplier databases, this NOx sensor is used in Ford 6.7L Power Stroke diesel SCR (AdBlue) systems.

Common system applications include:

• Ford F-250 Super Duty 6.7L Diesel (2017–present range depending on calibration)
• Ford F-350 Super Duty 6.7L Diesel
• Ford F-450 Super Duty 6.7L Diesel
• SCR (Selective Catalytic Reduction) diesel emission systems

Fitment is strictly based on OE number matching:
HC3A-5L248-CB / A2C10697900-01 / SNS361

OE cross-reference data confirms this sensor is part of the Ford 6.7L Power Stroke NOx sensor family used in SCR aftertreatment systems.

Technical Description

This NOx sensor measures nitrogen oxide concentration in diesel exhaust gases and sends real-time data to the engine control module (ECM).

It is a key component of the SCR (Selective Catalytic Reduction) system, which injects DEF/AdBlue to reduce NOx emissions and maintain compliance with emissions regulations.

The sensor is designed for high-temperature exhaust environments and continuous monitoring in heavy-duty diesel applications.

FAQ

Is this sensor upstream or downstream?

This OE family is used in Ford 6.7L SCR systems, and can appear in either NOx1 or NOx2 position depending on calibration and model year.

Is this sensor interchangeable with similar Ford part numbers?

Not recommended. Ford NOx sensors are ECU-calibrated, and even small suffix differences (CB / CA / CC variants) can change compatibility.

Why do multiple codes exist for the same sensor?

Because Ford and suppliers (Continental/Vitesco) use multiple internal and service-level part numbers for the same SCR system component.
