Brake Pedal Position Sensor?!?!? Hey guys hopefully you can help,
I have a 2000 Trans Am, 90k, and it has the ABS In Op light and the TCS light on.
When I press the TCS button it does nothing, but it is lit up.
The code for it is C0045. Brake Pedal Position Sensor Circuit B (Subfault).
My first question would be "Where is the Brake Pedal Position Sensor located?"
And my second question would be, what exactly does "Circuit B Subfault" mean?
I'm trying to figure out if this is a fairly easy fix, it sounds pretty pinpointed but I don't understand the code lingo and can't find any information about it.
I will also say, the tire sizes are a bit mismatched from stock, and the rear end has been replaced at some point. It also has drilled and slotted rotors, but only on the back. Not sure if any of these things have anything to do with the code, just trying to give the most information that I can. Thank you.

Just google it and you'll get more information on the problem than any of us can type here. There are entire sites dedicated to these codes.

Thank you, I looked underneath there and I assume its NOT the Brake Light Switch that is actually touching the brake pedal? It must be the sensor above that...
Could I ask, what might that sensor be called? I've searched everywhere, and it apparently isn't "brake pedal position sensor"... that part appears to be nonexistent for our cars.

It's been a while since I was under there, but I only recall one switch. There could be another one there for the cruise control, etc.
When I search for C0045, it comes up as a faulty speed sensor - not the switch.
