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

Based on Ford OEM catalog data and verified Bosch cross-reference listings, part number K2GA-5E145-AB is used in Ford Euro 6 diesel SCR (AdBlue) systems, mainly on the 2.0 EcoBlue diesel (EA288-based Ford Panther engine family).

Confirmed applications include:

• Ford S-MAX Mk2 (2018–2023) 2.0 EcoBlue Diesel
• Ford Galaxy Mk4 (2018–2023) 2.0 EcoBlue Diesel
• Ford Mondeo Mk5 (2019–2023 facelift) 2.0 EcoBlue Diesel
• Ford Transit / Transit Custom (selected Euro 6 SCR variants depending on calibration)

Fitment is strictly based on OE number matching:
K2GA-5E145-AB / Bosch 0281007421 / 2584865

Verified Cross-Reference (Important)

• Bosch confirms 0281007421 is a NOx sensor used in Ford diesel SCR systems with OE reference K2GA-5E145-AB
• Multiple EPC listings confirm fitment across Ford S-MAX / Galaxy / Mondeo 2.0 EcoBlue Euro 6 SCR vehicles
• Cross-platform compatibility also includes Mondeo MK5 and Galaxy CK platform diesel variants using the same SCR architecture

📌 Key point:
This sensor is part of Ford’s 2.0 EcoBlue Euro 6 SCR emissions system, and is ECU-coded (different sensors may look similar but are not interchangeable).

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 meet Euro 6 standards.

The K2GA-5E145-AB module is commonly used as:

• Downstream SCR NOx sensor (post-catalyst monitoring)
• Catalyst efficiency verification sensor
• Emissions feedback control sensor

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor signal or heater fault
• P220F / P229F / P11DC type codes
• Reduced engine power (limp mode)
• Increased emissions / AdBlue dosing errors

OE / Part Numbers

• K2GA-5E145-AB
• 2584865
• Bosch 0281007421
• K2GA-5E145-AC (updated revision in some cases)

FAQ

Is this sensor interchangeable with other Ford NOx sensors?

No. Ford SCR NOx sensors are ECU-coded. Even similar Bosch units (like 0281008680) may differ in calibration and cannot be safely interchanged.

Why do S-MAX, Galaxy, and Mondeo share this sensor?

Because they all use the same Ford 2.0 EcoBlue Euro 6 SCR diesel architecture, so emission components are shared.

Is this inlet or outlet sensor?

This reference is typically used as a post-SCR (outlet) NOx sensor, but exact position depends on vehicle calibration and exhaust layout.
