Fitment (Market-Validated Usage)

Based on OEM cross-reference listings and verified aftermarket catalog data, this NOx sensor is used in Nissan diesel SCR (AdBlue) systems, mainly on compact SUV Euro 6 diesel platforms.

Common system applications include:

• Nissan Qashqai II (J11) 1.5 dCi (Euro 6 SCR)
• Nissan Qashqai II facelift diesel variants (market dependent)
• Renault Kadjar 1.5 dCi (platform shared)
• Renault–Nissan 1.5 dCi Blue / K9K SCR systems

Fitment is strictly based on OE number matching:
22790HV80B / SNS1038

OE and aftermarket listings confirm this sensor is widely used on Nissan Qashqai J11 1.5 dCi SCR systems and shared Renault–Nissan diesel platforms.

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 ECU communication.

Symptoms / Fault Codes

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

OE / Part Numbers

• 22790HV80B
• SNS1038
• OE family used on Nissan Qashqai J11 diesel SCR systems

FAQ

Is this sensor vehicle-specific?

Yes. NOx sensors must match the exact OE number. Even small suffix differences (HV80B / HV90A / other revisions) can change calibration or installation position.

Why does Nissan appear with Renault?

Because Nissan and Renault share the same 1.5 dCi (K9K) SCR diesel platform, so the same NOx sensor is used across both 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.
