FAQ

Q1: Are 5461851, SNS3007, and A2C12428700-01 the same sensor?
A1: Yes. 5461851 is the Cummins OE number, SNS3007 is the sensor family code, and A2C12428700-01 is the Continental/Vitesco manufacturing reference for the same NOx sensor assembly used in SCR systems.

Q2: What vehicles use this sensor?
A2: It is widely used on Cummins-powered trucks (ISB, ISL, ISX platforms) across multiple OEMs including North American heavy-duty and medium-duty trucks with SCR/AdBlue systems.

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

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