Fitment (Market-Validated Usage)

Based on OEM cross-reference catalogs and verified aftermarket listings, this NOx sensor is used in Renault–Nissan diesel SCR (AdBlue) systems, mainly on Euro 6 small diesel passenger car platforms.

Common system applications include:

• Renault Megane IV 1.5 dCi / Blue dCi
• Renault Duster II 1.5 Blue dCi
• Renault Logan / Sandero / Lodgy / Dokker 1.5 dCi (Euro 6 variants)
• Nissan (badge-engineered Renault diesel platforms in selected markets)
• Dacia Duster / Sandero / Logan Blue dCi Euro 6 systems

Fitment is strictly based on OE number matching:
227904063R / SNS783 / A2C14717600-04

OE cross-reference data confirms this is a Continental/VDO SNS783 NOx sensor widely used across Renault Group 1.5 dCi Blue dCi SCR systems.

Aftermarket catalog listings consistently map this OE number to Renault Megane IV / Dacia Duster II 1.5 Blue dCi SCR applications.

Technical Description

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

It is part of the SCR (Selective Catalytic Reduction) system, which injects AdBlue (urea solution) into the exhaust stream to reduce NOx emissions and meet Euro 6 standards.

The sensor is an integrated electronic module designed for high-temperature exhaust environments with continuous monitoring and CAN communication.

FAQ

Is this sensor vehicle-specific?

Yes. NOx sensors must match the exact OE number. Even small suffix differences (783 / 904 / 918 variants) can change calibration, connector type, or ECU pairing.

Why do Renault, Nissan, and Dacia appear together?

Because these brands share the same 1.5 Blue dCi diesel SCR architecture across multiple platforms.

Can similar OE numbers be used instead?

Not recommended. These are ECU-calibrated emission components and must match exact OE specification to avoid SCR faults or limp mode.
