Guest ugp Posted April 29, 2012 Share Posted April 29, 2012 There should be a +5v feed to it, a VSS+, a VSS- and a ground. You can buzz out the + and - VSS sig's to the ecu connector. Link to comment Share on other sites More sharing options...

Check there's a 5v to one pin (ignition on), check there is a good ground too. As for the VSS +&-, pull the body connector out in the passengers footwell (big orange one), find out what pins the vss is on and check continuity between the sensor plug and the chassis plug. Sorry I've not got the pin outs here, it's hard enough writing this whilst driving. Ben Link to comment Share on other sites More sharing options...
