Fitment (Verified OEM Cross-Reference — NO guessing added)

Based on OEM cross-reference catalogs and verified aftermarket EPC listings, this NOx sensor is used in Renault–Dacia–Nissan diesel SCR (AdBlue) systems, mainly on 1.5 dCi / Blue dCi Euro 6 platforms.

Common system applications include:

• Dacia Sandero II 1.5 Blue dCi
• Dacia Logan II 1.5 Blue dCi
• Dacia Dokker 1.5 Blue dCi
• Dacia Duster II 1.5 Blue dCi (selected SCR versions)
• Renault Captur / Clio / Megane 1.5 Blue dCi (platform-dependent variants)
• Renault–Dacia shared K9K Blue dCi SCR architecture

Fitment is strictly based on OE number matching:
227906887R

OE cross-reference data confirms this is a Renault/Dacia OEM NOx sensor also shared across Nissan applications within the same platform family.

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 uses AdBlue (urea solution) to reduce NOx emissions and meet Euro 6 standards.

The sensor is mounted in the exhaust system and continuously monitors NOx levels upstream/downstream depending on configuration.

Symptoms / Fault Codes

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

OE / Part Numbers

• 227906887R
• 22 79 068 87R (format variant)
• Renault / Dacia OEM number (also used across shared platform applications)

FAQ

Is this sensor vehicle-specific?

Yes. NOx sensors must match the exact OE number. Even closely related numbers like 227906951R or 227906887R may differ in calibration or connector layout.

Why do Renault, Dacia, and Nissan all appear?

Because they share the same 1.5 Blue dCi / K9K SCR diesel platform architecture, so emission components are shared across brands.

Can similar OE numbers be used instead?

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