FAQ

Q1: Are 2894946 and 5WK96693A the same sensor?
A1: Yes. 2894946 is the Cummins OE number, and 5WK96693A is the sensor manufacturer reference used for the same NOx sensor module in SCR systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Cummins-powered heavy-duty trucks such as Kenworth, Peterbilt, Freightliner, and International models equipped with EPA10 SCR systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as inlet or outlet NOx sensor depending on exhaust configuration. Many Cummins SCR systems use similar sensor modules in multiple positions with different harness lengths.

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