This NOx sensor is part of the SCR aftertreatment system, used for measuring nitrogen oxide levels in exhaust gases to control AdBlue dosing and ensure Euro 6 compliance.

FUNCTION:

• Measures NOx concentration in exhaust gases
• Sends real-time data to ECU via CAN communication
• Controls AdBlue (DEF) injection for SCR efficiency
• Helps maintain emissions compliance and reduce engine derate

INSTALLATION POSITION:

• SCR system inlet or outlet sensor (depends on Volvo/Renault configuration)
• Mounted on exhaust pipe before or after SCR catalytic converter

FAQ:

Q1: Is this inlet or outlet sensor?
A1: 5WK97368 / 22827991 can be used as inlet or outlet depending on the SCR system layout and ECU calibration.

Q2: What vehicles does it fit?
A2: Volvo FH/FM Euro 6 trucks and Renault T series with SCR systems.

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

Q4: Are all 22827991 sensors the same?
A4: They belong to the same sensor family but may differ in harness length, connector type, and software calibration.

Q5: Does installation require programming?
A5: Some trucks require SCR reset or ECU adaptation after replacement.
