Title: wheres my speed sensor?
Post by: DazVR6 on 22 July 2006, 15:03

Anyone no where the engine speed sensor is located in a mk3 2.0 16v? is it on or near the gearbox/flywheel? i have a fualt code which tells me my idle rpm is to high do i change the speed sensor or can i adjust it another way?  :smiley:

Isnt there an idle screw on the throttle? I would try adjusting this first.

No, ABF engine ECU sets the idle speed.

Other way round, fuel relay 30, ECU relay 167.

Machanic that i use regularly,it was the crank speed sensor that was changed as water had leaked onto it and corroded it....are crank speed sensor/engine speed sensor same thing?

Yes.
Was the sensor actually causing a problem before it was replaced?

it was fine before being replaced..well up until coolent/water corroded it, crack in the coolent housing had been there for a while and when it split it soaked the sensor.Hope replacing sensor has nothing to do with it cutting out!!!
