2011 manual mazda 3 p0850 engine code clutch switch

Hi everyone, recently I got a yellow engine light reads out as clutch switch issue, I tested the switch and seems to work, also the car reacts to pressing the clutch, also I don't have any systems that don't work except for I-stop, but I think that is because of cold weather and a battery that is a little old. I am confused at what the issue is and how to fix it. Has anyone seen a similar thing?
