Universal reference NOx sensor SNS0303A used in various diesel vehicles equipped with SCR (Selective Catalytic Reduction) systems.
Compatible applications depend on OEM cross-reference and ECU calibration requirements.

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

Q2: Where is it installed?
A2: It is mounted in the exhaust system, typically upstream or downstream of the SCR catalyst depending on vehicle design.

Q3: What are symptoms of failure?
A3: Check engine light, SCR/AdBlue system warnings, fault codes, increased emissions, and possible engine power reduction.

Q4: Is it universal?
A4: Not fully universal. SNS0303A is a cross-reference type used across multiple brands, but exact compatibility depends on OEM part number match.
