Common applications include diesel aftertreatment systems using reference:

• 68171187AB

Designed for Euro 5 / Euro 6 SCR emission control systems.

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

Q2: Where is it installed?
A2: It is mounted on the exhaust system, typically before or after the SCR catalytic converter depending on system layout.

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 this interchangeable with other RAM NOx sensors?
A4: It is a specific revision (AB). Some cross-compatibility exists, but correct part number matching is required for proper calibration.
