Hmm...pressure sensor? I'm guessing that would be up by the master cylinder or abs motor to sense pressure on the system. I believe the only thing at the wheels is the sensor ring for wheel speed. Never really looked too closely but see what is plugged in/around the motor and cylinder. Try searching a bit on here or maybe someone with access to a manual or first hand experience will chime in and give you what you are looking for. I'm sure if you can locate it there are some specs it can be tested against for a definite answer on its condition. Or maybe I'm totally wrong, it is almost bed time for me...
