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

• Cummins ISB / ISL / ISX series (SCR-equipped variants)
• Freightliner, Kenworth, Peterbilt, International trucks (depending on emissions setup)
• 24V SCR diesel engine systems for on-road and off-road applications

OEM / Cross reference numbers:

• 5WK96713A
• 5WK96713

This is a smart NOx sensor module used in SCR exhaust aftertreatment systems to measure nitrogen oxide levels and control AdBlue dosing for emissions compliance. It is a CAN-based electronic sensor used in modern diesel emission systems.

FUNCTION:

• Measures NOx concentration in diesel exhaust gases
• Sends real-time data to ECU/ACM via CAN (J1939) communication
• Controls AdBlue/DEF injection for SCR catalyst efficiency
• Helps maintain Euro / EPA emissions compliance and prevent engine derate

INSTALLATION POSITION:

• SCR system inlet or outlet sensor (depends on OEM configuration)
• Mounted between DPF and SCR catalyst or downstream of SCR unit

IMPORTANT NOTE:
Cummins NOx sensors are “smart sensors” with integrated control electronics, meaning they can fail due to:

• Internal module failure
• CAN communication faults
• Heater circuit failure

Always confirm correct calibration and connector type before ordering.

FAQ:

Q1: Is this inlet or outlet sensor?
A1: It can be used as inlet or outlet depending on Cummins SCR system configuration. ECU defines the function by calibration.

Q2: What vehicles use it?
A2: Cummins-powered heavy-duty trucks and equipment using SCR systems (Freightliner, Kenworth, Peterbilt, etc.).

Q3: What are failure symptoms?
A3: SCR warning light, engine derate, NOx sensor fault codes, AdBlue system errors, or limp mode.

Q4: Are 5WK96713 and 5WK96713A interchangeable?
A4: 5WK96713A is an updated version in many catalogs, but compatibility must match OEM number exactly.

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