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

Based on OEM Hyundai/Kia parts listings and multiple verified aftermarket EPC sources, part number 29650-2U260 is used in Hyundai/Kia Euro 6 diesel SCR (AdBlue) systems, mainly on 1.6 CRDi C-segment SUV/hatch platforms (Tucson / Sportage generation 2018–2021).

Common system applications include:

• Hyundai Tucson TL (2018–2020) 1.6 CRDi Euro 6 SCR
• Kia Sportage QL (2019–2021) 1.6 CRDi Euro 6 SCR
• Hyundai/Kia shared 1.6 CRDi SCR diesel architecture

Fitment is strictly based on OE number matching:
29650-2U260

EPC and aftermarket listings confirm this part is a Hyundai/Kia NOx sensor used on Tucson and Sportage Euro 6 SCR systems, typically listed as a direct replacement for factory-installed SCR NOx sensor assemblies.

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

The SNS-type sensor module is mounted in the exhaust system and continuously monitors NOx levels upstream or downstream depending on SCR configuration.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor communication faults
• P2200 / P229F / U029D type codes (platform dependent)
• Reduced engine power (limp mode)
• Increased emissions

OE / Part Numbers

• 29650-2U260
• Hyundai/Kia SCR NOx sensor family (Tucson / Sportage 1.6 CRDi platform)
• 296502U260 (format variant used in aftermarket listings)

FAQ

Is this sensor vehicle-specific?

Yes. Hyundai/Kia NOx sensors are ECU-calibrated. Even small OE differences (2U100 / 2U200 / 2U260 / 2U400) can change connector shape, cable length, or ECU mapping.

Why do Tucson and Sportage share this sensor?

Because both use the same 1.6 CRDi Euro 6 SCR diesel platform architecture, so emission components are shared across Hyundai/Kia SUVs.

Can similar OE numbers be used instead?

Not recommended. These are emission-critical ECU-coded components and must match exact OE specification to avoid SCR faults, limp mode, or incorrect NOx readings.
