A1: It measures nitrogen oxide levels in exhaust gases and sends real-time data to the ECU to control DEF/AdBlue dosing and ensure emissions compliance.

Q2: Where is it installed?
A2: It is installed in the exhaust system, typically before or after the SCR catalyst depending on engine configuration.

Q3: What are symptoms of failure?
A3: Engine warning light, SCR system fault codes, increased emissions, and possible engine derating or reduced performance.

Q4: Is it compatible with all Caterpillar engines?
A4: No, compatibility depends on engine model, emissions standard, and SCR system setup.
