Customer Question

I own a 1986 Ford Bronco 2, and I have been having some major issues with the throttle position sensor. I have installed 3 new ones now, and two new plugs. When I hook up the voltmeter to the resistance wire I usually get a reading of .76 volts. When I push on the throttle it drops to zero volts. I'm completely stuck here.

hello, my name is ***** ***** I will be glad to assist you. please allow me a couple of minutes to gather some basic info.

ok, first, you need to be measuring voltage not resistance. the center wire in the tps connector wire is what you need to measure. the center wire will read between 0 and 5 volts when moving the accelerator pedal from idle to full. at idle it should be around .5 and at wide open should be 4.8 volts

Thats what I've been doing. The resistance is in volts. When I push the throttle the voltage goes to .76 volts to 0 volts instead of up.
Expert:  roy replied 7 months ago.

resistance is not volts, 2 separate things.

are you checking the center wire???
