FITMENT:
Compatible with Cummins diesel engines used in DAF trucks and other heavy-duty applications equipped with SCR (AdBlue/DEF) systems, including:

• DAF CF / XF Euro 5 / Euro 6 (Cummins-powered configurations)
• Cummins ISB / ISL SCR diesel systems (application dependent)
• Selected heavy-duty 24V commercial truck SCR systems

OEM / Cross reference numbers:

• 4326768
• 5WK97347A / 5WK9 7347A

This NOx sensor is used in diesel exhaust aftertreatment systems to monitor nitrogen oxide levels and control AdBlue dosing for emissions compliance.

FUNCTION:

• Measures NOx concentration in exhaust gas stream
• Sends real-time data to ECU via CAN (J1939 communication)
• Controls SCR/AdBlue injection for optimal catalyst efficiency
• Helps meet Euro 5 / Euro 6 emissions standards and prevent engine derate

INSTALLATION POSITION:

• SCR system inlet or outlet sensor (depends on OEM configuration)
• Mounted on exhaust pipe between DPF and SCR catalyst or after SCR unit

IMPORTANT NOTE:
Cummins/DAF SCR systems may use multiple NOx sensor positions (inlet/outlet). The exact function depends on ECU calibration, not only the part number.

FAQ:

Q1: Is this inlet or outlet sensor?
A1: It can be used as inlet or outlet depending on DAF/Cummins SCR configuration.

Q2: What vehicles use it?
A2: DAF CF/XF trucks with Cummins engines and SCR emissions systems.

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

Q4: Are 4326768 and 5WK97347A interchangeable?
A4: Yes, 5WK97347A is the Continental reference for Cummins OEM 4326768.

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