Re: Using technoresearch VDSTS tools to reset TPS?
jerryz, in my VDSTS there is a reading for throttle position in degrees. On the menus look for 'Options' then selsect 'Channels/Mode'. I can configure it to show different settings: air temp, engine temp, throttle position, RPM, MPH, etc. Look through the menus and you should find the selection for what is displayed.
Regardless, if you've got the earlier TPS that you adjust by lossening the two screws and turning to get 150mV then doing that with a multimeter is just fine. Once adjusted VDSTS should show the throttle position somewhere between 2.3 and 2.7 degrees when fully closed. The reading depends on your model, I think most are 2.7.
