Default 01435 - Brake Pressure Sensor 1 (G201)

This error came up today when I ran a VCDS scan, but with no extra wording to specify the type of fault (Ross-Tech have 3 variants but this was "vanilla" which they don't include). It did have the additional "35-10 Intermittent" comment.

Now I do recall the other day a single yellow warning light came on when I started the car, but I was only moving it a short distance and everything seemed normal so I didn't look at it closely. The light didn't come on again on any subsequent start so I'm not 100% sure what it was, probably the ESP warning on its own. Though whenever I've seen that in the past it's usually combined with something else.

I think this was shortly after I'd been testing the brake light switch, so operating the pedal in unusual ways. Could that have logged something to upset it or should I be looking for something potentially failing? I've cleared the fault to see if it returns.
Another thing I also noticed today was an example of the "sluggishness" when moving off. As commonly seen before it was after stopping at a T-junction after gentle continuous braking, holding on the footbrake then pulling out into a main road. As ever a "twitch" of the right foot resumed normal operation. But I'll comment on that in its own thread.

Ross-Tech does suggest that the 3 variants of this code (No or Incorrect Basic Setting / Adaptation, Electrical Fault in Circuit, Implausible Signal) can be linked to the brake pedal switch, so I'm hoping it's just a side-effect of my testing.
If it isn't where is the G201 sensor, is it integrated into the ABS block or separate?
