Re: Phase sensor fault?
Very, very interesting.....As I have said in previous posts regarding my engine management light, it too came on after I had my belts etc changed. I took it back to the dealer saying it had never come on before and now suddenly after you replace the belt it on....Well they didn't like that and dismissed it so fast I immediately thought something is going on here.
They diagnosed the fault firstly stating it was the coil pack. However upon inspection all was fine so they rewired it and reset the comp.
Next week light appeared again this time they said no idea so we cleaned the connectors.....Again the light appeared i go down to these inapt fools again and then am told its an injector!
So i tell them where to go literally and left it. I have since found a new Alfa specialists closer to home who i will get to check it out. the light comes on every week and as you have stated there are no running problems with the car.
So what exactly does this phaze sensor do? And is it somewhat easy to damage when changing the belts if it is and knowing when my light came on the day after i will do a little more investigation and seek legal redress.
