CEL - P2000?

[Sepp]

Good day
CEL came on and I read P130, O2 sensor and P2000 NOx trap below efficiency. Any idea what the NOx trap refers to on this car? (1.9 liter 4 cyl)
Light went out after a few start stop cycles.

thanks

NOx trap, that sounds like a Cat convertor. The normal Cat below efficiency codes are P0420 and P0430.

Couldn't find P2000 in any code reference I have on these cars.

The P2000 probably came up as a symptom of the P0130 code.
