Part Details:

Kubota 1J631-19370 NOx Sensor (Post)

The Kubota 1J631-19370 NOx Sensor (Post) is an OEM exhaust emission monitoring component used in Kubota diesel engines equipped with Selective Catalytic Reduction (SCR) systems. This sensor is positioned downstream of the SCR catalyst (post-catalyst) and continuously monitors the concentration of nitrogen oxides (NOx) in the exhaust gas after the urea/DEF treatment process.

It provides critical feedback to the Engine Control Unit (ECU) to optimize the DEF injection rate, ensuring compliance with EPA Tier 4 Final / EU Stage V emissions standards.
