The pedal position sensor is just held in by a ring clip. It needed a good tug to get it out, but wasn't difficult to get out. Mine was actually the connector in the end, but I bought a brand new PPS and fitted that, so I think I still have my original one that was tested good. I cant remember if it sold or not before I left with a few other bits, but if I still have it and you're in no great rush, give me a nudge around Christmas time and I'll see if I can dig it out.
