I would suggest having the vehicle put on a scanner and monitor the operating parameters of the sensor for heater signal operation and sensor performance. You may not have overlooked anything. However, without knowing what the sensor is actually doing nand reading, you will be chasing your tail

if the switch is not working it will have to be replaced you don`t fix them. but you don`t say what problem your having with it.

If you follow up the brake pedal towards the steering column, you will see the switch.The switch can be at the front of the pedal or at the back of the pedal. It's not a difficult replacement, it's just hard to lay on your back in that small space and do the job. The part costs about $10.00. The question I have is why are you looking to replace? The faults are usually brake lights stay on which will kill your battery , or switch is bad and brake lights don't come on when pedal is depressed. I would first check for blown fuses, and blown bulbs. If you need any additional help please get back to me. GOOD LUCK FREIND.
