FAQ

Q1: Are 5WK96764A, A045S168, and A2C89789500-01 the same sensor?
A1: Yes. 5WK96764A is the Continental/Vitesco reference, A045S168 is a Cummins internal code, and A2C89789500-01 is the manufacturer OE reference for the same NOx sensor used in ISF SCR systems.

Q2: What engines use this sensor?
A2: It is mainly used on Cummins ISF2.8 and ISF3.8 engines found in light-duty trucks, vans, and commercial vehicles equipped with SCR (AdBlue) emissions systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as inlet or outlet depending on SCR configuration. Many ISF systems use similar NOx sensors 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 dosing to reduce emissions and maintain SCR efficiency.
