Denso 4N14 P0489 dtc

[cccoding]

Good morning,
i need EGR off on this file, which i think is done properly, but the car turns on MIL light and throw P0489 when EGR is disconnected. When connected, it is always opened.
So, is there an error in the file?

Thanks

PD: when removing P0489, it throw P0000 and MIL is still on.
