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

Based on Bosch aftermarket catalog data and verified Ford OEM cross-reference listings, part number KV61-5E145-AE (2552693) is used in Ford Euro 6 diesel SCR (AdBlue) systems, mainly on 1.5 / 1.6 EcoBlue diesel platforms (Ford Transit Connect / Transit Courier and related small commercial vehicles).

Confirmed applications include:

• Ford Transit Connect 1.5 EcoBlue Euro 6 SCR (2016–2023)
• Ford Transit Courier 1.5 EcoBlue Euro 6 SCR (2016–2023)
• Selected Ford small commercial SCR diesel variants (platform dependent)

Fitment is strictly based on OE number matching:
KV61-5E145-AE / 2552693 / Bosch 0281007424

Verified Cross-Reference (Important)

• Bosch catalog confirms 0 281 007 424 = NOx sensor used in Ford SCR systems with OEM references KV61-5E145-AE and 2552693
• Same listing shows interchangeability within Ford SCR family: KV61-5E145-AB / AC / AD / AE variants and 2552693 all belong to same NOx sensor platform group
• Ford Transit Connect 1.5 EcoBlue application confirmed in SCR exhaust system listings for this Bosch unit

📌 Key point:
This is a Bosch SCR NOx sensor for Ford 1.5 EcoBlue diesel, and it is ECU-coded (different suffix revisions like AB/AC/AD/AE may not be interchangeable without calibration match).

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 Bosch 0281007424 module is typically used as:

• SCR catalyst inlet or outlet NOx monitoring sensor
• AdBlue dosing feedback control sensor
• Emission efficiency verification sensor

Symptoms / Fault Codes

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

OE / Part Numbers

• KV61-5E145-AE
• 2552693
• Bosch 0281007424 / 0 281 007 424
• KV61-5E145-AB / AC / AD / AE (revision family)
• Ford 1.5 EcoBlue SCR NOx sensor family

FAQ

Is this sensor interchangeable with other Ford NOx sensors?

Not always. Ford uses ECU-coded SCR sensors. Even within KV61 family, AB / AC / AD / AE revisions may require exact matching calibration.

Why do Transit Connect and Courier share this sensor?

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

Can aftermarket versions work?

Yes, but only if Bosch spec (0281007424) and correct calibration version are matched — otherwise SCR faults or limp mode may occur.
