FAQ

Q1: Is 5WK96751 used on Cummins EPA10 engines?
A1: Yes. 5WK96751 is a NOx sensor commonly used in Cummins EPA10 SCR systems for heavy-duty diesel engines.

Q2: What vehicles use this sensor?
A2: It is widely used on Cummins-powered trucks such as Kenworth, Peterbilt, Freightliner, and International with SCR (AdBlue) emissions systems.

Q3: Are 5WK96751A / B interchangeable?
A3: They are revisions within the same sensor family, but exact compatibility depends on ECU calibration and harness length, so match by OEM number when possible.

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 dosing to reduce emissions and maintain SCR efficiency.
