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

• Cummins ISB / ISL / ISX series (specific SCR configurations)
• Freightliner, Kenworth, Peterbilt, International applications (depending on OEM setup)
• Industrial and agricultural 24V Cummins SCR systems

OEM / Cross reference numbers:

• 5WK96713A
• 5WK9 6713A

Based on OEM cross-reference data, this is a NOx sensor used in SCR exhaust aftertreatment systems, typically functioning as a smart sensor module communicating with the ECU via CAN/J1939 for emissions control.

FUNCTION:

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

INSTALLATION POSITION:

• SCR system inlet or outlet (depends on engine and exhaust layout)
• Mounted between DPF and SCR catalyst or after SCR unit

FAQ:

Q1: Is this inlet or outlet sensor?
A1: It can be used as inlet or outlet depending on Cummins SCR configuration. Position is defined by ECU calibration and exhaust layout.

Q2: What vehicles use it?
A2: Cummins-powered heavy-duty trucks, buses, and machinery with SCR systems (application varies by OEM).

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

Q4: Is 5WK96713A interchangeable with other Cummins NOx sensors?
A4: No. Even similar sensors differ in calibration, connector type, and software version.

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