Title: 1.8 8v gti sensor plug....
Post by: brad88 on 24 October 2010, 19:06

hi people,
just wondering what the black 2 wire plug is for on the back of the throttle body, both wires look to be broke, and the revs fluctuate ever so slightly between 1300rpm down to 800rpm, could that be the cause?
cheers, brad :D

Apparently a common fault mate, I need to check mine aswell.
I think you can test if it is working when wired in by leaving the ignition on and listening for a click when you open and close the throttle

no that just shows you the idle switch is adjusted properly. to test em electrically start engien and open throttle just off the stop, say to 1.5krpm or so. press the wot switch on top of the throttle, revs should drop then rise again when you release
