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

Based on Ford OEM catalog data and verified Bosch cross-reference listings, part number MT71-5E145-AB (0281008426) is used in Ford Euro 6 diesel SCR (AdBlue) systems, mainly on Transit Connect / Transit Courier 1.5 TDCi EcoBlue diesel platforms (Euro 6 emissions systems).

Confirmed applications include:

• Ford Transit Connect 1.5 TDCi Euro 6 SCR (2016–2023)
• Ford Transit Courier 1.5 TDCi Euro 6 SCR (2016–2023)
• Selected Ford small commercial diesel SCR variants depending on VIN

Fitment is strictly based on OE number matching:
MT71-5E145-AB / 0281008426 / 2635477

Verified Cross-Reference (Important)

• Multiple aftermarket listings confirm MT71-5E145-AB = Bosch 0281008426 NOx sensor for Ford Transit Connect / Courier SCR systems
• Same listing data confirms interchange with OE 2635477 / MT71-5E145-AB Ford SCR NOx sensor family
• Product catalogs consistently show this sensor used in Ford 1.5 TDCi Euro 6 SCR diesel emissions systems

📌 Key point:
This is a Bosch SCR NOx sensor used in Ford 1.5 EcoBlue diesel platforms, and it is ECU-coded (not interchangeable with different Ford NOx revisions).

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 Bosch 0281008426 module is typically used as:

• Inlet or outlet NOx sensor (depending on vehicle configuration)
• SCR efficiency monitoring sensor
• AdBlue dosing feedback sensor

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor communication fault
• P2200 / P229F / U029D type codes (Ford-specific variants possible)
• Reduced engine power (limp mode)
• Incorrect AdBlue consumption or dosing faults

OE / Part Numbers

• MT71-5E145-AB
• 0281008426
• 2635477
• Ford EcoBlue SCR NOx sensor family (1.5 diesel platform group)

FAQ

Is this sensor interchangeable with other Ford NOx sensors?

No. Ford uses ECU-coded SCR sensors. Even if connectors look similar, each NOx sensor is calibrated for a specific engine and position (inlet/outlet).

Why do Transit Connect and Transit Courier share this sensor?

Because both use the same Ford 1.5 TDCi EcoBlue Euro 6 SCR diesel architecture, so emission components are shared.

Is this inlet or outlet sensor?

It can be used as either depending on configuration, but most applications are SCR system monitoring positions (pre/post catalyst depending on layout).
