Fitment

Fits for:

• Cummins ISB / ISX / ISC diesel engines (EPA10 / Euro 5 SCR systems depending on calibration)
• Heavy-duty trucks: Freightliner, Kenworth, Peterbilt, International (Cummins-powered platforms)
• Engine: Cummins SCR / aftertreatment systems (DEF / AdBlue equipped vehicles)
• Position: Exhaust NOx sensor (inlet or outlet depending on SCR layout)
• OE / Cross References: 2872082 / 5WK96676 / 5WK96676A / 3687387 / 2894942 / 2872028 / SNS-type NOx sensor family

FAQ

Q1: Are 2872082 and 5WK96676 the same sensor?
A1: Yes. 2872082 is the Cummins OE number and 5WK96676 is the Continental/Vitesco reference used for the same NOx sensor assembly in SCR systems.

Q2: What engines use this sensor?
A2: It is commonly used on Cummins EPA10 SCR diesel engines such as ISB, ISX, and other heavy-duty applications in trucks from Freightliner, Kenworth, Peterbilt, and International.

Q3: Is this inlet or outlet sensor?
A3: It can be used as inlet or outlet depending on SCR system configuration. Cummins often uses the same sensor family with different harness lengths for different positions.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) levels in exhaust gases and sends data to the ECU, which controls AdBlue (DEF) dosing to reduce emissions and maintain SCR efficiency.
