how to test the tps sensor?

ok i found the link to the ford fuel injection on testing the tps but i think im missing something....

can someone give a quick explanation on it?
do you test it with out the plug and measure the ohms as i open the throttle to see for smooth increase? where would it start and stop?

im assuming this is done with the truck off...

on the ford fuel injection it talks about volts... is that key on checking?

how do you get the idle reading? is it with the throttle closed? i would think that wouldnt be idle... or does it have to be running to check it....

i dont know why im having a hard time with this lol

Hope this gives you the edge you need

Key must be on

You should find what you need here

Ford Bronco And F-150 Links - EEC-IV; SELF TEST & Diagnostic Trouble Code (DTC), Overview, etc.

here is another---


Ford Fuel Injection » Throttle Position Sensor (TPS) this may be the one you have

and another

Hope that helps

The chart at the bottom of the page with the expected voltage values is not enough for you to determine if the TPS is bad?
