To put it in detail, it seems that the overall number of revolutions, including idle revolutions, is 100 to 150 rpm, high.
Until now, during the idling of the P range after complete warming, it was 750 rpm, but now it is 850 th.
It is 500 to 550 when it is D creeping in the D range after full warming, but now it is 650 rpm.

Also, even if you turn off the accelerator after driving, the rotation speed will not fall from a certain value (average 800 rpm), and the accelerator on state will continue subtly.
It is higher than the number of revolutions during creep running so far.
I think that learning after resetting the ECU has already ended, so there seems to be a problem with some parts or sensors.

I would like to ask this question separately in the future.
Thank you for your consideration.

Mr.Mindful
Thank you for answering.
Although it was not possible to clean the OCV filter, it seems that the OCV filter has been replaced by changing it.
