Macca 1 Posted November 4, 2003 Report Share Posted November 4, 2003 First off, well done to whoever has made this site, very cool.Second: My car has suffered a major loss of power following a replaced head gasket. Diagnostics show a fault with the Hall sensor, but being a 94 VR6 it doesn't HAVE a Hall sensor. The fault cannot be removed by just resetting the system.Any ideas as to what is wrong ?!

phat28vr6 0 Posted November 4, 2003 Report Share Posted November 4, 2003 Does your engine have a distributer? Or is it D.I.S. with the coil pack... Link to post Share on other sites
acf8181 0 Posted November 4, 2003 Report Share Posted November 4, 2003 a '94 will have a coilpack.think only '92 models had dizzy's, as my '93 is coilpack. Link to post Share on other sites
brett 0 Posted November 4, 2003 Report Share Posted November 4, 2003 same thing happened to my car, hall sender on a distributorless engine turned out to be cam pos sensor Link to post Share on other sites
Macca 1 Posted November 4, 2003 Author Report Share Posted November 4, 2003 Thanks guys, i think you're right and my 94 doesn't have a distributor. Looks like the car DOES have a hall sensor though, despite what VW garage say, so i guess the fault is with the hall sensor or with cam position sensor, as you say. Link to post Share on other sites

Macca 1 Posted November 7, 2003 Author Report Share Posted November 7, 2003 VW were quoting the price of a crank position sensor. useless. Cam pos sensor is £35 as you say. Link to post Share on other sites
brett 0 Posted November 7, 2003 Report Share Posted November 7, 2003 vw can sometimes be annoyingly dumb and expensive,thats why i use an independant garage.glad u got it sorted Link to post Share on other sites
Macca 1 Posted November 23, 2003 Author Report Share Posted November 23, 2003 Hi again all. Had the whole hall/cam sensor thing looked into, and apparently although it is showing as a fault, its fine!. So are all the rest of the electrics. All he could tell me was that manifold vacuum pressure was very low - 10 inches instead of 18.I have no idea what this means.the original mechanic that replaced the head gasket and essentially caused the problem is sticking to his word and is taking the head off again on tues to see if he put it back together wrongly. Anyone have any advice for him?? Link to post Share on other sites
