FITMENT
Compatible with Cummins diesel engines equipped with SCR (Selective Catalytic Reduction) AdBlue emission systems requiring NOx monitoring.
Common applications include:

• Cummins ISX / X15 series engines (SCR-equipped variants depending on calibration)
• Heavy-duty truck platforms using Cummins aftertreatment systems
• Industrial diesel engines and commercial vehicles with Euro 5 / Euro 6 SCR systems
• OEM SCR systems using Cummins/IVECO integrated emissions architecture

Using reference numbers:

• SNS0154D
• A3C00895700-01 / A3C0089570001
• Common SCR NOx sensor family used across Cummins engine platforms

This sensor is part of the exhaust aftertreatment system that monitors NOx levels and ensures proper AdBlue/DEF dosing for emissions compliance.

FAQ
Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide (NOx) levels in the exhaust system and sends real-time data to the ECU to control AdBlue injection and reduce emissions.

Q2: Where is it installed?
A2: It is installed in the SCR exhaust system, typically upstream or downstream of the catalytic converter depending on engine configuration.

Q3: What are symptoms of failure?
A3: Check engine light, SCR/DEF warning messages, NOx sensor fault codes, reduced engine power, or limp mode activation.

Q4: Is SNS0154D interchangeable with other Cummins NOx sensors?
A4: It is part of a Cummins SCR sensor family, but compatibility depends on engine model, ECU calibration, and emission system version. Always verify OEM cross-reference before replacement.
