This NOx sensor is used in diesel exhaust aftertreatment systems for NOx monitoring (AdBlue/DEF SCR system). It is typically used as inlet or outlet sensor depending on vehicle configuration.

Installed in exhaust system either before or after SCR catalyst depending on OEM layout. MAN Euro 5/Euro 6 systems commonly use these interchangeable Continental/Bosch sensor variants with different harness lengths.

FUNCTION:

• Measures nitrogen oxide (NOx) concentration in exhaust gases
• Sends data to ECU for AdBlue dosing control
• Maintains SCR efficiency and emissions compliance
• Helps prevent engine derate or fault codes

INSTALLATION POSITION:

• SCR system inlet or outlet (depends on OEM configuration)
• Mounted on exhaust piping between DPF and SCR catalyst or tailpipe section

FAQ:

Q1: Are all these part numbers interchangeable?
A1: They are cross-referenced OEM numbers, but exact fit depends on vehicle model, harness length, and SCR position (inlet/outlet).

Q2: Which trucks does it fit?
A2: MAN TGX, TGS, TGA, TGM, and TGL Euro 5/6 trucks depending on emissions system setup.

Q3: What are failure symptoms?
A3: SCR warning light, AdBlue faults, engine derate, incorrect NOx readings, or limp mode.

Q4: Is programming required after replacement?
A4: Some MAN trucks require diagnostic reset or SCR adaptation after installation.
