• OE / Cross References: 4954222 / 5WK96620A / 7757182 / 5WK96620B / 4984577 / SNS-type NOx sensor family / Cummins shared platform reference 2894940

FAQ

Q1: Are 4954222 and 5WK96620A the same sensor?
A1: Yes. 4954222 is the DAF/Nissan OE number and 5WK96620A is the Continental/Vitesco reference used for the same NOx sensor module in SCR systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on heavy-duty diesel trucks such as Nissan UD Quon/Quester models and some DAF-based SCR systems depending on engine and emissions setup.

Q3: Is this inlet or outlet sensor?
A3: It can be used as inlet or outlet depending on SCR configuration. Most systems using this family share identical sensor hardware with different harness lengths and mounting positions.

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