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

Based on Ford OEM catalog data and verified Bosch cross-reference listings, part number GK21-5E145-AD (2601469) is used in Ford Euro 6 diesel SCR (AdBlue) systems, mainly on 2.0 EcoBlue diesel engines in Transit Custom / Transit V363 platforms.

Confirmed applications include:

• Ford Transit Custom Mk8 (2018–2023) 2.0 EcoBlue SCR
• Ford Transit V363 (2016–2023) 2.0 EcoBlue SCR
• Ford Tourneo Custom 2.0 EcoBlue SCR diesel variants
• Selected Transit platform Euro 6 SCR diesel configurations

Fitment is strictly based on OE number matching:
GK21-5E145-AD / 2601469 / Bosch 0281007071

Verified Cross-Reference (Important)

• EPC listings confirm GK21-5E145-AD = Bosch 0281007071 NOx sensor used on Ford Transit Custom / Transit V363 SCR systems
• Cross-reference data shows same sensor also listed under Ford number 2601469 and interchangeable Bosch families in SCR system catalogues
• Transit Custom V362/V363 diesel SCR system compatibility confirmed in multiple OEM parts catalog records

📌 Key point:
This is a Ford EA288/2.0 EcoBlue SCR NOx sensor, and it is ECU-coded—different suffixes (AD / AC / AE) are not always interchangeable.

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 0281007071 module is typically used as:

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

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor signal or communication fault
• P2200 / P229F / U029E type codes
• Reduced engine power (limp mode)
• Increased AdBlue consumption or dosing errors

OE / Part Numbers

• GK21-5E145-AD
• 2601469
• Bosch 0281007071
• GK21-5E145-AE (revision variant, sometimes interchangeable depending on ECU software)

FAQ

Is this sensor interchangeable with other Ford NOx sensors?

No. Ford uses ECU-coded SCR sensors. Even within Transit systems, AD / AE / AC revisions may require matching calibration.

Why do Transit Custom and Transit V363 share this sensor?

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

Can aftermarket versions work?

Yes, but quality varies. Low-quality sensors often cause SCR faults or incorrect NOx readings, so matching Bosch-spec calibration is critical.
