Fuel Trim

Hello. New here. I was wondering if anyone knows the proper fuel trim readings for a 2004 V70 B5244S engine?
And if there is anywhere I can find the correct parameters for what I am seeing from the OBDII.
Thank you very much for any help.

Less than +/-10% is good, under +/-5% is excellent! It's a mechanical machine. Therefore some variation is expected.
This is for long term fuel trim ^

That above percentage is valid for all vehicles.

What is your obd2 reading out?

Thanks for the response.
It shows Fuel Trim 1x2 and goes between 0.8% - 1.6% while idiling.

Don't worry about short fuel from. Long is the only one to worry about
