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

Based on OEM Hyundai/Kia EPC listings and verified aftermarket SCR catalog data, part number 29650-2U000 (SNS0826A) is used in Hyundai/Kia Euro 6 diesel SCR (AdBlue) systems, mainly on 1.6 CRDi diesel compact SUV and C-segment platforms (Kona / Tucson / Sportage depending on emission position and market calibration).

Confirmed applications include:

• Hyundai Kona OS 1.6 CRDi Euro 6 SCR (2017–2020 diesel variants)
• Hyundai Tucson TL / TLE 1.6 CRDi SCR
• Kia Sportage QL / QLE 1.6 CRDi SCR
• Hyundai/Kia shared 1.6 CRDi SCR diesel architecture

Fitment is strictly based on OE number matching:
29650-2U000 / SNS0826A

Verified Cross-Reference (Important)

• OEM aftermarket listings confirm 29650-2U000 = SNS0826A NOx sensor used on Hyundai Kona / Tucson / Kia Sportage SCR diesel systems
• Multiple EPC listings show same sensor family used across Hyundai/Kia 1.6 CRDi Euro 6 SCR platforms
• SNS0826A belongs to the Continental NOx sensor family commonly used in Hyundai/Kia SCR exhaust systems

Technical Description

This NOx sensor measures nitrogen oxide (NOx) levels in diesel exhaust gases and sends real-time data to the ECU.

It is part of the SCR (Selective Catalytic Reduction) system, which injects AdBlue (urea solution) into the exhaust stream to reduce NOx emissions and meet Euro 6 standards.

The SNS0826A module is typically used in 1.6 CRDi SCR systems, often mounted either upstream or downstream of the SCR catalyst depending on vehicle configuration.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor communication faults
• P2200 / P229F / U029E type codes (platform dependent)
• Reduced engine power (limp mode)
• Increased emissions

OE / Part Numbers

• 29650-2U000
• SNS0826A
• A2C17251000-01 / A3C05797900-01 (supplier equivalents depending on revision)
• Hyundai/Kia 1.6 CRDi SCR NOx sensor family

FAQ

Is this sensor interchangeable with other 2U series sensors?

No. Even though it is part of the same SCR system family, Hyundai/Kia NOx sensors are ECU-calibrated. Variants like 2U000 / 2U200 / 2U220 differ in wiring, software, and exhaust position.

Why do Kona, Tucson, and Sportage share this sensor?

Because they all use the same Hyundai/Kia 1.6 CRDi Euro 6 SCR diesel architecture, so emission components are shared.

Can similar SNS codes be used instead?

Not recommended. Incorrect SNS revision will cause SCR faults, incorrect NOx readings, or limp mode.
