FITMENT:
Compatible with heavy-duty diesel trucks using Cummins/Paccar SCR emission systems, including:

• Kenworth T800
• Peterbilt 389
• International Trucks ProStar / LoneStar (selected configurations)

OEM / Cross reference numbers:

• 5WK96692 / 5WK9 6692A
• 2894945 / 2872297 / 5293295 (common OE cross references)

Based on OEM interchange data, this sensor is commonly used on Cummins EPA10 SCR systems across Kenworth, Peterbilt, and International platforms, typically as part of the upstream/downstream NOx monitoring setup.

Used in diesel exhaust aftertreatment system for NOx monitoring (DEF/AdBlue SCR system).
Installed in exhaust system (inlet or outlet position depending on SCR configuration and OEM calibration).

FUNCTION:

• Measures nitrogen oxide (NOx) concentration in exhaust gases
• Sends real-time data to ECU/ACM for SCR dosing control
• Optimizes AdBlue injection and emission efficiency
• Helps prevent engine derate and SCR fault conditions

INSTALLATION POSITION:

• SCR system inlet or outlet sensor (depends on OEM layout)
• Typically mounted between DPF outlet and SCR catalyst or after SCR unit

FAQ:

Q1: Is this inlet or outlet sensor?
A1: It can be either depending on truck configuration. OEM part number and position on the exhaust must be matched.

Q2: What engines does it fit?
A2: Commonly used on Cummins EPA10 engines in Kenworth T800, Peterbilt 389, and International ProStar/LoneStar trucks.

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

Q4: Are all 5WK96692 sensors interchangeable?
A4: No. Even with the same base number, calibration and harness length can vary by OEM application.

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