FITMENT
Compatible with Chrysler, Jeep, and RAM diesel vehicles equipped with SCR (Selective Catalytic Reduction) AdBlue emission systems requiring NOx monitoring.
Common applications include FCA diesel platforms using reference:

• SNS0961
• A2C19211200-01

Typically used in Euro 5 / Euro 6 diesel aftertreatment systems (depending on engine and market).

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/DEF injection and reduce emissions.

Q2: Where is it installed?
A2: It is installed in the exhaust system, usually before or after the SCR catalytic converter depending on vehicle configuration.

Q3: What are symptoms of failure?
A3: Check engine light, SCR/AdBlue system warnings, NOx sensor fault codes, reduced engine performance, or limp mode activation.

Q4: Is SNS0961 interchangeable across Chrysler, Jeep, and RAM?
A4: Yes, it is a cross-platform SCR sensor used across FCA diesel applications, but exact fitment still depends on engine type and calibration.
