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: 5594608 / SNS1094 / 5WK96736A / A063W651 / A062U293 / 9.3560.1 / DN08120016 / 119143 / CASALS 68917

FAQ

Q1: Are 5594608 and SNS1094 the same sensor?
A1: Yes. 5594608 is the Cummins OE number and SNS1094 is a common sensor reference used for the same NOx sensor module in SCR systems.

Q2: What vehicles use this sensor?
A2: It is used across Cummins-powered diesel trucks with SCR systems, including medium and heavy-duty commercial vehicles depending on emission level (Euro 5 / Euro 6 / EPA10 variants).

Q3: Is this inlet or outlet sensor?
A3: It can be used as inlet or outlet NOx sensor depending on the SCR system configuration. Many Cummins systems use similar NOx sensors in multiple positions.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) concentration in exhaust gases and sends data to the ECU, allowing precise AdBlue dosing to reduce emissions and keep the SCR system efficient.
