FAQ

Q1: Are 4384394, SNS3013, and A2C14507700-04 the same sensor?
A1: Yes. 4384394 is the Cummins OE number, SNS3013 is the sensor family code, and A2C14507700-04 is the Continental/Vitesco manufacturing reference for the same NOx sensor module used in SCR systems.

Q2: What engines use this sensor?
A2: It is commonly used on Cummins QSB and related SCR-equipped engines found in off-highway machinery, construction equipment, and some on-highway applications depending on emissions calibration.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either inlet or outlet depending on SCR system configuration. The same sensor family is used with different harness lengths and mounting positions across 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, allowing precise AdBlue dosing for emissions compliance and SCR efficiency.
