FAQ

Q1: Are 4327153, A047R390, and 5WK96760B the same sensor?
A1: Yes. 4327153 is the Cummins OE number, A047R390 is a Cummins internal reference, and 5WK96760B is the Continental/Vitesco sensor code used for the same NOx sensor assembly.

Q2: What engines use this sensor?
A2: It is mainly used on Cummins ISX15 / ISX EPA10 engines in heavy-duty trucks such as Freightliner Cascadia, Kenworth, Peterbilt, and International highway trucks.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either inlet or outlet NOx sensor depending on SCR layout. Many Cummins systems use identical sensor bodies 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.
