Fitment

Fits for:

• Cummins diesel engines with SCR (AdBlue / DEF) emission systems
• Medium-duty and heavy-duty commercial trucks (various OEM applications)
• Applications using Cummins aftertreatment NOx monitoring system
• Engine platforms: ISB / ISL / ISX (depending on calibration and SCR layout)
• Position: Exhaust NOx sensor (inlet or outlet depending on SCR configuration)
• OE / Cross References: 5593958 / A062U293 / A3C00894900-03 / 5593958RX / SNS-type NOx sensor family / Cummins SCR sensor module

FAQ

Q1: Are 5593958, A062U293, and A3C00894900-03 the same sensor?
A1: Yes. These are interchangeable cross-reference numbers used for the same NOx sensor module in SCR diesel aftertreatment systems.

Q2: What vehicles use this sensor?
A2: It is used across multiple diesel truck platforms equipped with SCR systems, depending on OEM integration of Cummins engines and aftertreatment systems. Common applications include medium and heavy-duty commercial vehicles.

Q3: Is this inlet or outlet sensor?
A3: It can be used as inlet or outlet NOx sensor depending on the aftertreatment layout. Many SCR systems use multiple identical NOx sensors in different positions with different harness lengths.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) concentration in exhaust gases and sends data to the ECU. The system then adjusts AdBlue dosing to reduce emissions and maintain SCR efficiency.
