Hello,

You have done all that I would recommend, the only thing that I can think of is the pressure sensor is not earthing to ground when it is operating. Did you test the wire to earth at the sensor connector to check the gauge?

I have never physically looked at one so I dont know if it earths through it's body or through a second wire but I would say that would be the problem if you have tested the gauge from there.

i think sensors earth's itself so thats not the prob, does any1 know the resistance or ohms (think thats wat the auto leccy says) ov the pressure switch itself, cheers lads
