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

Based on OEM Hyundai/Kia parts catalogs and verified aftermarket EPC listings, part number 29640-2F150 is used in Hyundai/Kia diesel SCR (AdBlue) systems, mainly on 2.0 CRDi Euro 6 SUV platforms.

Common system applications include:

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

Fitment is strictly based on OE number matching:
29640-2F150 / SNS0801A / A2C17245300-02

OE cross-reference data confirms this is a Continental SNS0801A NOx sensor used across Hyundai Santa Fe IV and Kia Sorento III SCR diesel systems.

Multiple EPC listings also confirm the same OE number applies to Santa Fe IV (TM/TMA) and Sorento III (UM) Euro 6 SCR diesel configurations.

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 operates under high-temperature exhaust conditions and provides continuous emissions feedback for SCR dosing control and catalyst efficiency monitoring.

Symptoms / Fault Codes

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

OE / Part Numbers

• 29640-2F150
• SNS0801A
• A2C17245300-02
• Hyundai / Kia SCR NOx sensor family (Santa Fe IV / Sorento III platforms)

FAQ

Is this sensor vehicle-specific?

Yes. Hyundai/Kia NOx sensors are ECU-calibrated. Even small differences (2F120 / 2F140 / 2F150 variants) can change calibration, connector type, or mounting position.

Why do Santa Fe and Sorento share this sensor?

Because both models use the same Hyundai/Kia 2.0 CRDi Euro 6 SCR diesel platform architecture.

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.
