I am changing out my 70mm TB and stock plenum for a 75MM TB and ported and polished plenum today. I need to know what the voltage needs to be when I switch the throttle position sensor. I heard a while back something about closest to 1 volt with out getting here ex. .99 volts but I can't remember if it was at idle or car off and pedal to the floor. Anyone know

on the 4.6 stang,the tps is none adjustible,the only thing you do is bolt it on,and your done

key on engine off .98 or so

i thought that you did not have to adjust them[8D]

mdvaldosta

your not "supposed" to have to, but installing aftermarket throttlebodies, adjusting the idle, etc. often requires you to

Thanks for clearing that up MD

Hey thanks MD

Instead of probing for voltage, just unplug and read the resistance across the sensor. Then set the other accordingly.

It's the way I did mine. Then you don't have to penetrate any wires.

Hey rtm what should the resistance be then I am not familiar with what it should be. What 2 of the 3 contacts will I be testing too.

I can't remember which of the three you use, so just read all of them off of your sensor while it is on the stock TB.

Probe pins 1,2---1,3---2,3. Write down the resistance you read between them. Then when you put the sensor on the new TB, snug it down, re-read the pins and adjust until they are the same as the stock readings.

Just set your meter up to read ohms. It is the symbol shaped like a horseshoe. Set the scale to read two decimal places.

I don't recall ever seeing a range of what it should be when dealing with resistance. Just voltage.
