FAQ

Q1: What is 5WK96692A used for?
A1: It is a NOx (nitrogen oxide) sensor used in Cummins SCR diesel emissions systems to monitor NOx levels and control DEF (AdBlue) dosing for emission compliance.

Q2: Which engines use this sensor?
A2: It is commonly used on Cummins EPA10 SCR engines such as ISB, ISL, ISX, and QSX platforms in heavy-duty commercial trucks.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either inlet or outlet NOx sensor depending on the SCR system configuration. Many Cummins systems use similar sensors in multiple positions.

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