Fitment (Market-Validated Usage)

Based on OEM cross-reference data, Continental/VDO catalog listings, and aftermarket supplier documentation, this NOx sensor is used in Renault–Nissan diesel SCR (AdBlue) systems, mainly on compact SUV and C-segment Euro 6 diesel platforms.

Common system applications include:

• Nissan Qashqai II (J11) 1.5 dCi / 1.6 dCi diesel SCR systems
• Renault Kadjar 1.5 dCi / 1.6 dCi
• Nissan X-Trail T32 (selected diesel SCR variants)
• Renault–Nissan shared Euro 6 diesel SCR platforms

Fitment is strictly based on OE number matching:
22790HV90A / SNS964 / A2C19783300-03

OE cross-reference data confirms this is a Continental/VDO SNS964 NOx sensor used across Renault-Nissan SCR systems.

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 emissions monitoring and ECU communication.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning

• Reduced engine power (limp mode)
• Increased emissions

OE / Part Numbers

• 22790HV90A
• SNS964
• A2C19783300-03
• Continental / VDO sensor family: SNS964

FAQ

Is this sensor vehicle-specific?

Yes. NOx sensors must match the exact OE number. Even small suffix differences (HV90A / HV90B / SNS964 variants) can change calibration or wiring configuration.

Why do Renault and Nissan appear together?

Because both brands share the same Renault–Nissan diesel SCR architecture across multiple Euro 6 platforms.

Can similar OE numbers be used instead?

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