Fitment (Verified OEM / Market Usage)

Based on OEM cross-reference catalogs and verified aftermarket listings, this NOx sensor is used in Nissan–Renault diesel SCR (AdBlue) systems, primarily on Navara / NP300 pickup diesel platforms.

Common system applications include:

• Nissan Navara NP300 (D23) 2.3 dCi
• Nissan NP300 Pickup 2.3 dCi (Euro 6 SCR variants)
• Nissan Frontier / Navara regional diesel SCR variants
• Renault–Nissan shared 2.3 dCi diesel SCR platforms

Fitment is strictly based on OE number matching:
227905JU0A / SNS991 / A3C01433800-02

OE cross-reference data confirms this is a Continental SNS991 NOx sensor used across Nissan NP300/Navara D23 SCR systems.

Aftermarket catalogs also consistently map this OE number to Navara D23 2.3 dCi SCR applications with multiple equivalent references across suppliers.

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

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

• 227905JU0A
• SNS991
• A3C01433800-02
• 22790-5JU0A (format variant)

FAQ

Is this sensor vehicle-specific?

Yes. NOx sensors must match the exact OE number. Even small suffix differences (JU0A / HV80B / FV1A variants) can change calibration, connector type, or mounting position.

Why do Nissan and Renault appear together?

Because they share diesel SCR architecture across certain 2.3 dCi / NP300/Navara platforms, using identical emission system components.

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.
