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

Based on OEM Hyundai/Kia SCR catalog references and verified aftermarket EPC listings, part number 29640-2FRC0 (SNS800) is used in Hyundai/Kia Euro 6 diesel SCR (AdBlue) systems, mainly on 2.2 CRDi diesel performance SUV / sedan platforms (Genesis / Stinger diesel variants depending on market).

Confirmed applications include:

• Kia Stinger 2.2 CRDi Euro 6 SCR diesel
• Genesis G70 2.2 CRDi Euro 6 SCR diesel
• Hyundai/Kia shared 2.2 CRDi SCR architecture (regional calibration dependent)

Fitment is strictly based on OE number matching:
29640-2FRC0 / SNS800

📌 Verified cross-reference evidence:

• Listings confirm 29640-2FRC0 = SNS800 NOx sensor used on Kia Stinger / Genesis G70 2.2D (2018–) SCR systems.
• Multiple OEM aftermarket listings consistently show same OE mapping for Hyundai/Kia 2.2 CRDi SCR platforms.

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 comply with Euro 6 standards.

The SNS800 module is typically used in 2.2 CRDi SCR systems, monitoring exhaust NOx levels for catalyst efficiency and AdBlue dosing control.

Symptoms / Fault Codes

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

OE / Part Numbers

• 29640-2FRC0
• SNS800
• A2C10697900-01 (common supplier reference)
• Hyundai/Kia SCR NOx sensor family (2.2 CRDi platform group)

FAQ

Is this sensor vehicle-specific?

Yes. Hyundai/Kia NOx sensors are ECU-coded. Even if physically similar, SNS800 is specifically tuned for 2.2 CRDi SCR systems (Stinger / G70 diesel platforms).

Why do Stinger and Genesis G70 share this sensor?

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

Can similar OE numbers be used instead?

Not recommended. Even small differences in SNS codes (SNS800 vs SNS900 / SNS801 etc.) can cause SCR faults or incorrect NOx readings.
