FITMENT
Compatible with Komatsu heavy-duty machinery such as excavators (PC700 series) equipped with diesel SCR (Selective Catalytic Reduction) emission systems requiring NOx monitoring.
Common applications include equipment using part numbers:

• 4326766
• 5WK97346A

Used in industrial diesel engines with Euro emission-standard SCR/AdBlue systems.

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 and reduce emissions.

Q2: Where is it installed?
A2: It is installed in the exhaust after-treatment system, typically near the SCR catalyst on heavy machinery engines.

Q3: What are symptoms of failure?
A3: Warning lights, SCR system fault codes, reduced engine performance, or emissions derating in heavy equipment.

Q4: Is it compatible with all Komatsu PC700 machines?
A4: No, compatibility depends on engine model, emission configuration, and SCR system setup.
