Hi Doc, some more info for the thread;
tps overall resistance; 6.25 k ohm ( yellow/black )
throttle lower position; 1.095 k ohm ( red/black )
throttle high position ; 6.05 k ohm
( all measured ref to " ground or lower section ie green/black" and tps disconnected from ecu.
Voltages;
yellow/black +4.97 volt
red/black idle 0.482 volt wot 4.45 volt
green/black 0 volt ( the black meter probe )
Voltage increases in a linear way from lower to higher position.
Hope this helps to assist with the gathering of data from the members involved.
Bonus footage; iacv operation on my bike, as usual a bit vague, the video editing program had trouble at 5% slow motion but what happens is ; on startup the iacv opens 65 steps and then closes 12 steps with a cold engine and 35 wiith a warm engine.
This happens in the blink of an eye as demonstrated at the very end of the video so i slowed it down to count the steps and direction, open and close.
the ecu does not know what position the iacv is at startup , so it always commands the valve open with 65 pulses, it then makes a decision to close x many steps based on the temperature of the eot sensor.
Whilst i had the black plastic throttle body covers off i found that mine were made on 27 july 2010, another clue.
