Fitment (Market-Validated Usage)

Based on OEM cross-reference catalogs, Vitesco/Continental documentation, and aftermarket supplier listings, this NOx sensor is used in Renault–Nissan–Dacia diesel SCR (AdBlue) systems on K9K / M9R platform vehicles.

Common system applications include:

• Renault Duster II 1.5 Blue dCi
• Renault Kadjar 1.5 / 1.6 dCi
• Renault Trafic III 1.6 / 2.0 dCi
• Renault Master III 2.3 dCi (selected SCR variants)
• Dacia Duster / Sandero / Logan Blue dCi (Euro 6 diesel)
• Nissan NV300 / NV400 diesel SCR systems
• Opel / Vauxhall Movano / Vivaro (platform-shared variants)

Fitment is strictly based on OE number matching:
227901461R / SNS917 / A2C16634700-01

OE cross-reference data confirms this is a Continental/Vitesco SNS917 NOx sensor widely used across Renault-Nissan-Mercedes light commercial diesel SCR architectures.

Technical Description

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

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

The sensor is designed for high-temperature exhaust environments and continuous monitoring, with integrated electronics and ECU communication.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor circuit or communication faults
• P2200 / P229F type codes (system dependent)
• Reduced engine power (limp mode)
• Increased emissions

OE / Part Numbers

• 227901461R
• SNS917
• A2C16634700-01 / A2C16634700-03
• Renault / Nissan / Dacia shared OE family

FAQ

Is this sensor vehicle-specific?

Yes. NOx sensors must match the exact OE number. Even small suffix differences (00Q0A / 1461R / SNS917 variants) can change calibration or connector configuration.

Why do multiple brands appear in fitment?

Because Renault, Nissan, and Dacia share the same diesel SCR platform architecture, so the same NOx sensor is used across multiple vehicle lines.

Can similar OE numbers be used instead?

Not recommended. These are ECU-calibrated emission components and must match exact OE specification.
