Fitment (Verified OEM Cross-Reference)

Based on OEM listings and multiple aftermarket catalog sources, this NOx sensor is used in Renault Euro 6 diesel SCR (AdBlue) systems, mainly on 2.0 TCe / 2.0 dCi high-output passenger car platforms.

Common system applications include:

• Renault Talisman 2.0 dCi / 2.0 TCe (Euro 6 SCR variants)
• Renault Espace V 2.0 dCi
• Renault Koleos II 2.0 dCi (selected SCR configurations)
• Renault Laguna-derived 2.0 diesel SCR architecture (platform-dependent)

Fitment is strictly based on OE number matching:
227905118R / SNS941A

OEM cross-reference and marketplace listings confirm this sensor is used in Renault Espace V and Talisman 2.0 diesel SCR systems with the SNS941A Continental/Vitesco sensor family.

Technical Description

This NOx sensor measures nitrogen oxide (NOx) 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 emissions monitoring, with integrated electronics and CAN communication to the engine control system.

Symptoms / Fault Codes

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

OE / Part Numbers

• 227905118R
• SNS941A
• A3C00365600-03 (commonly listed supplier reference in aftermarket catalogs)

FAQ

Is this sensor vehicle-specific?

Yes. NOx sensors must match the exact OE number. Even small suffix differences (118R / 507R / 342R variants) can change calibration, connector layout, or ECU pairing.

Why do Talisman, Espace, and Koleos appear together?

Because they share Renault’s 2.0 dCi / 2.0 TCe Euro 6 SCR architecture, which uses the same NOx sensor family.

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.
