tps evaluating for ii issues

[max]

Max & Doc: I am going to ride the bike today to runs errands, and bring my VOM along. If/when the low idle conditions appears I will immediately stop and measure the voltage at the TPS Black/Red connection. I will do this with the engine running, and the TPS plugged in, and then repeat it with the engine off. Each time I will twist the throttle to see if/how the voltage changes. Hopefully this will provide some useful information. If the low idle condition does not appear I will unplug the TPS and ride it for several miles and see what happens. What do you guys think? I'll report back this evening.

Dave, that sounds real good om both idea's, if you can capture it in the act and even take a picture and or video that would settle it.

Actually pb's post made me think, if you can measure all three pins whilst in low idle you may be able to prove if the ground return ( black green ) is higher than 0 volt or not, if it is more than 0 volt that would point to bad connection in ground return path to ecm, you can even measure if the engine has stalled.
To give you an idea about the current through the tps circuit( 5 v divided by 6000 ohm ) is less than 1 mA, a lot can go wrong at such a low current.

One idea i had was to make a gadget that can be plugged in between the tps and connector that would indicate an led on over 0.6 volts, easy to do since a transistor switches on at 0.6 volts, all you need is 2 resistors an led and a npn transistor, but the vom is of course much more accurate.

Thank you, pb and pdedse; max
