Maintenance/Repairs

I own a 2004 toyota 4runner. I am getting a P0504 code on my OBD2 sensor. My brake light comes on sporadically when I accelerate from a stop. It tends to be on more frequently when the car is still cold and when the weather is colder. All of my brake lights work like normal with no flickering, my car drives like normal and I don’t notice any issues. I have replaced the brake switch and checked all of the fuses. All of the fuses seem to be in working order and the new switch didn’t change anything. The VSC Trac, VSC OFF lights have both been on since I got the vehicle a year and a half ago but it doesn’t impair my driving at all. There is no check engine light on either. What am I likely dealing with here?
