Fitment

Fits for:

• Cummins diesel engines with SCR (AdBlue / DEF) emissions systems
• Medium-duty and heavy-duty commercial vehicles depending on OEM integration
• Engine platforms: Cummins ISB / ISL / ISX (SCR-equipped variants)
• Position: Exhaust NOx sensor (inlet or outlet depending on SCR layout)
• OE / Cross References: 5WK96614I / A0009058511 / SNS614I / A2C12459800-01 / 5801363754 / 89463-E0012 (platform-related cross applications may exist)

FAQ

Q1: Is 5WK96614I a Cummins NOx sensor?
A1: Yes. 5WK96614I is a NOx sensor reference used in SCR diesel emissions systems for Cummins-related applications depending on OEM configuration.

Q2: What does this sensor do?
A2: It measures nitrogen oxide (NOx) levels in exhaust gases and sends data to the ECU to control AdBlue dosing, reducing emissions and maintaining SCR efficiency.

Q3: Is it inlet or outlet sensor?
A3: It can be used as either inlet or outlet NOx sensor depending on the SCR system design.

Q4: Is this sensor interchangeable with other brands?
A4: It is commonly used across multiple OEM platforms (Cummins, Mercedes-style SCR systems, etc.), but fitment depends on ECU calibration and connector type.
