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

• ISX / X15 (selected SCR configurations)
• ISB / ISL / ISM (depending on emissions system setup)
• Freightliner / Kenworth / Peterbilt / International applications

OEM reference numbers:

• 4327153
• 5WK96760A

This NOx sensor is used in diesel exhaust aftertreatment systems to measure nitrogen oxide levels and support SCR control strategy for AdBlue dosing. It is a smart CAN-based sensor module used in 24V systems.

Based on OEM interchange data, 4327153 is the Cummins part number and 5WK96760A is the Continental/Bosch sensor reference used as its direct replacement equivalent.

FUNCTION:

• Measures NOx concentration in exhaust gas stream
• Sends real-time data to ECM/ACM via CAN/J1939 communication
• Controls DEF (AdBlue) injection for SCR efficiency
• Ensures EPA / Euro emissions compliance

INSTALLATION POSITION:

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

FAQ:

Q1: Is this inlet or outlet sensor?
A1: It depends on the engine and aftertreatment layout. Cummins 4327153 / 5WK96760A is used in SCR systems where it may function as inlet or outlet depending on calibration.

Q2: What vehicles use it?
A2: Common in Cummins-powered Freightliner, Kenworth, Peterbilt, and International trucks with EPA10/EPA13 SCR systems.

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

Q4: Is 4327153 interchangeable with 5WK96760A?
A4: Yes, 5WK96760A is a widely used aftermarket/OE cross reference for Cummins 4327153.

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