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

Based on Hyundai/Kia EPC cross-reference data and verified aftermarket SCR catalog listings, part number 29640-2F410 is used in Hyundai/Kia Euro 6 diesel SCR (AdBlue) systems, mainly on 2.0 CRDi / 2.2 CRDi diesel SUV platforms (Santa Fe / Sorento generation depending on exhaust layout and emission calibration).

Confirmed applications include:

• Hyundai Santa Fe IV (TM / TMA) 2.0 CRDi Euro 6 SCR
• Kia Sorento III (UM) 2.0 / 2.2 CRDi Euro 6 SCR
• Hyundai/Kia shared SCR diesel SUV architecture

Fitment is strictly based on OE number matching:
29640-2F410

Verified Cross-Reference (Important)

• Aftermarket EPC listings confirm 29640-2F410 is part of the Hyundai/Kia SCR NOx sensor family used on Santa Fe / Sorento diesel Euro 6 systems
• Same SCR platform is shared with closely related Hyundai/Kia NOx sensors such as 29640-2F140 / 2F150 / 2F170 series, confirming this is part of the same emissions architecture family

📌 This confirms it is not a standalone sensor design, but a platform-specific SCR NOx sensor revision within Hyundai/Kia 2.0–2.2 CRDi Euro 6 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 injects AdBlue (urea solution) into the exhaust stream to reduce NOx emissions and meet Euro 6 standards.

The sensor is used for engine-out or catalyst-out NOx monitoring, depending on system layout, and is essential for SCR dosing accuracy and emissions compliance.

Symptoms / Fault Codes

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

OE / Part Numbers

• 29640-2F410
• Hyundai/Kia SCR NOx sensor family (2.0 / 2.2 CRDi platform group)
• 296402F410 (catalog format variant)
• Related family: 29640-2F140 / 2F150 / 2F170 series

FAQ

Is this sensor interchangeable with other Hyundai/Kia NOx sensors?

No. Even though it belongs to the same SCR family, Hyundai/Kia NOx sensors are ECU-calibrated. Different suffixes (2F410 vs 2F140 etc.) indicate different sensor calibration or placement.

Why do Santa Fe and Sorento use similar sensors?

Because both use the same Hyundai/Kia 2.0 / 2.2 CRDi Euro 6 SCR diesel architecture, so emission components are shared.

Can similar-looking sensors be used instead?

Not recommended. These are ECU-coded emissions components—wrong calibration will trigger SCR faults or limp mode.
