FAQ

Q1: Are 4327153, 5WK96742B and A2C12500400-01 the same sensor?
A1: Yes. 4327153 is the Cummins OE number, 5WK96742B is the sensor manufacturer reference, and A2C12500400-01 is another OEM reference used for the same NOx sensor assembly in SCR systems.

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

Q3: Is this inlet or outlet sensor?
A3: It can be used as inlet or outlet depending on SCR configuration. Many EPA10 Cummins systems use the same sensor type in both positions with different harness routing.

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