How is it done?!
RAVE says remove drive belt tensioner (easy, done), unplug connector (tricky but done) then remove the sensor.
I can't find any way to get any kind of tool on it!
There's no room for a spanner and I can't get a socket on it. Long sockets hit the bracket the tensioner mounts to and short sockets don't go on. Even if I could get a socket on there doesn't look to be room to get the ratchet on.
I'd like to avoid removing the oil filter or the water pump hose if possible. I'm connecting up an oil pressure gauge so it all needs rebuilding again to test and will need dismantling again to refit the switch.
