Fitment

Fits for:

• Cummins diesel engines with SCR (AdBlue / DEF) emissions systems
• Heavy-duty trucks and commercial vehicles using Cummins aftertreatment systems
• Engine platforms: ISB / ISL / ISX (depending on SCR configuration)
• Position: Exhaust NOx sensor (inlet or outlet depending on system layout)
• OE / Cross References: 5WK97102 / A2C93842800-01 / A2C93842800 / A2C16257000-01 / 5WK97102A / SNS102 / Cummins SCR NOx sensor family

FAQ

Q1: Is 5WK97102 the same as A2C93842800-01?
A1: Yes. These are cross-referenced part numbers for the same NOx sensor module used in Cummins SCR emissions systems.

Q2: What vehicles use this sensor?
A2: It is used on Cummins-powered diesel trucks and equipment equipped with SCR (AdBlue) systems, including various medium and heavy-duty commercial applications.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either inlet or outlet NOx sensor depending on SCR system configuration. Many Cummins systems use identical sensor modules in different positions.

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