I have just replaced the g65 sensor which was coming up with an open short to ground error and replaced it with a genuine new one. Whilst I had the old one off I could hear a lot of hissing coming from the valve I removed it from. This went on for about 10-15 minutes until I managed to find the new sensor which I misplaced! I connected it all back up and now vcds is coming up with open short to plus. Is this because the system lost too much pressure and now won't turn on? Will a regas fix this? The old sensor was definitely faulty because it came apart in my hands as I was removing it and the pcb had a burnt out chip.
