FITMENT
Compatible with MAN commercial vehicles and buses equipped with SCR (Selective Catalytic Reduction) AdBlue emission systems requiring NOx monitoring.
Common applications include:

• MAN TGA
• MAN TGX
• Neoplan buses
• Engines: D2066 diesel platforms
  Using reference numbers:
• 51154080019 / 51.15408.0019

Typically used in SCR exhaust aftertreatment systems for emission control and AdBlue dosing regulation.

FAQ
Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide (NOx) levels in the exhaust system and sends real-time data to the ECU to control AdBlue/DEF injection and reduce emissions.

Q2: Where is it installed?
A2: It is installed in the SCR exhaust aftertreatment system, usually upstream or downstream of the catalytic converter depending on vehicle configuration.

Q3: What are symptoms of failure?
A3: Check engine light, SCR/AdBlue system warnings, NOx sensor fault codes, reduced engine power, or limp mode activation.

Q4: Is 51154080019 the same as 5WK96790B?
A4: Yes, 51154080019 is the MAN OEM part number and 5WK96790B is the sensor manufacturer reference for the same SCR NOx sensor unit.
