FAQ

Q1: Are 5462439, A059A962, and SNS0935A the same part?
A1: Yes. 5462439 is the Cummins OE number, SNS0935A is the sensor family designation, and A059A962 / AAA2001380000 are supplier and manufacturing cross-references for the same NOx sensor assembly used in SCR systems.

Q2: What vehicles use this sensor?
A2: It is widely used across Cummins-powered heavy-duty and medium-duty trucks in North America and global markets, especially ISB, ISL, and ISX SCR-equipped applications.

Q3: Is this inlet or outlet sensor?
A3: It can be configured as either inlet or outlet depending on the aftertreatment layout. The same sensor family is used with different harness lengths and calibrations.

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