Gibbo GTI 0 Posted May 31, 2007 Can anyone tell me what the voltage on pin3 of the ECU should be with the throttle fully open. Share this post Link to post Share on other sites
Hilgie 16 2 Cars Posted June 1, 2007 It is not a potmeter, it's a switch. Nothing really complicated. I don't know the voltage, but I do know that the microswitches inside breakdown quite often. Share this post Link to post Share on other sites
Gibbo GTI 0 Posted June 1, 2007 Is there 2 microswitches in the throttle switch? I can hear 1 microswitch operate as the throttle is opened but thats it. Share this post Link to post Share on other sites
boombang 2 Posted June 1, 2007 The one you hear is the closed one opening up, the other is silent and at near full throttle - just check continuity through rather than voltage. Share this post Link to post Share on other sites
