FAQ

Q1: Are 68085740AA and 5WK96730 the same sensor?
A1: Yes. 68085740AA is the OE number used on Ram/Cummins applications, and 5WK96730 is the sensor reference used for the same NOx sensor module in SCR systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Ram 2500, 3500, 4500, and 5500 trucks equipped with the 6.7L Cummins diesel engine and SCR (AdBlue) emissions system from 2013–2015.

Q3: Is this inlet or outlet sensor?
A3: It is typically used as a downstream (outlet) NOx sensor in the SCR system on Cummins 6.7L applications.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) levels in exhaust gases and sends real-time data to the ECU to control AdBlue dosing, helping reduce emissions and maintain SCR efficiency.
