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

Based on OEM Ford parts catalogs, aftermarket EPC listings, and cross-reference databases, this NOx sensor is used in Ford diesel SCR (AdBlue) systems, mainly on 2.0 EcoBlue and selected commercial diesel platforms depending on emission calibration.

Common system applications include:

• Ford Transit Connect 1.5 / 2.0 EcoBlue diesel SCR (selected variants)
• Ford Transit Custom 2.0 EcoBlue (Euro 6 SCR variants)
• Ford Tourneo Connect EcoBlue diesel models
• Ford commercial diesel SCR platforms using MT7Z / KV series NOx architecture

Fitment is strictly based on OE number matching:
2465443 / MT7Z-5L248-AC / 938321

OEM and aftermarket cross-reference data confirms this sensor belongs to Ford’s MT7Z/LC3Z-style NOx sensor family used across EcoBlue SCR systems, with multiple OE supersessions depending on model year and calibration. (eurostarter.de)

Ford EPC cross-reference listings also show MT7Z-5L248-A / HC3Z / PC3Z variants within the same NOx sensor architecture family depending on engine and emission level.

Technical Description

This NOx sensor measures nitrogen oxide 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 and continuous monitoring, with integrated electronics and CAN communication to the engine control system.

Symptoms / Fault Codes

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

FAQ

Is this sensor vehicle-specific?

Yes. Ford NOx sensors are ECU-calibrated. Even small suffix changes (MT7Z / HC3Z / KV61 variants) can change connector layout, length, or software pairing.

Why do multiple Ford part numbers exist for similar sensors?

Because Ford frequently supersedes NOx sensor part numbers across model years while keeping similar physical architecture, especially in EcoBlue diesel systems.

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.
