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

Based on OEM cross-reference listings and verified aftermarket catalogs, this NOx sensor is used in Ford diesel SCR (AdBlue) systems, mainly on 1.5 TDCi EcoBlue Euro 6 passenger car and light commercial platforms.

Common system applications include:

• Ford Transit Connect 1.5 TDCi EcoBlue (Euro 6 SCR)
• Ford Tourneo Connect 1.5 TDCi EcoBlue
• Ford Transit Custom (selected 1.5 EcoBlue variants depending on emission system setup)

Fitment is strictly based on OE number matching:
KV61-5L248-AC / 2461610

OE cross-reference listings confirm this sensor is used on Ford 1.5 EcoBlue diesel SCR systems with Continental/VDO-based NOx sensing architecture.

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

The sensor is designed for high-temperature exhaust environments with integrated electronics and continuous monitoring via CAN communication.

Symptoms / Fault Codes

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

OE / Part Numbers

• KV61-5L248-AC
• KV61-5L248-AD (variant seen in aftermarket listings)
• 2461610
• Ford EcoBlue NOx sensor family reference

FAQ

Is this sensor vehicle-specific?

Yes. Ford NOx sensors are tightly ECU-matched. Even small suffix changes (AC / AD revisions) can affect calibration or connector layout.

Why does it appear on Transit Connect and Tourneo Connect?

Because both models share the same 1.5 TDCi EcoBlue SCR diesel platform, using identical emission components.

Can similar OE numbers be used instead?

Not recommended. These are ECU-calibrated emission sensors and must match exact OE specification to avoid SCR faults or limp mode.
