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

• Cummins ISB / ISL / ISX series (selected SCR configurations)
• Freightliner, Kenworth, Peterbilt, International trucks (depending on SCR setup)
• 24V SCR diesel engine systems in on-road and off-road equipment

OEM / Cross reference numbers:

• 5WK96713A
• 5WK96713

This is a smart NOx sensor module used in SCR aftertreatment systems to monitor nitrogen oxide levels and control AdBlue dosing for emissions compliance.

FUNCTION:

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

INSTALLATION POSITION:

• SCR system inlet or outlet sensor (application-dependent)
• Mounted in exhaust line between DPF and SCR catalyst or downstream of SCR unit

FAQ:

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

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

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

Q4: Are 5WK96713 and 5WK96713A the same?
A4: 5WK96713A is an updated/revised version of 5WK96713 in many applications, but compatibility must be confirmed by OEM number.

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