2002 XLT 4.0 SOHC Throttle Position Sensor Test/Mod

[Jonny Jekyll]

I want to retest my TPS to make sure it's at 96v, I've done it before but I can't remember which terminals go where. And if you need a ground or which setting to use for the volt meter. I can't find thread which has the pictures of how to use the volt meter with it. Is there anyone out there who has done this and has the pictures for it? I can't find any videos either.

I also have aftermarket, modded heads, Pacesetter headers, true dual 2" (all the way, to keep and add even more torque) exahust with 2 8 inch Cherry Bombs and no cats; a Superchips Flashpaq programmer, an Accel Super Coil and an AEM cold air intake. You would not believe how fast this thing is
Here's a video of the before, during and after of my exhaust. Give it a THUMBS UP, there's a lot of trolls out there who like to downvote just to spread hate.

Here's a tutorial & video.
If you don't have a BackProbe for your VoltMeter, a PaperClip\SmallNail straightened+sharpened works too.

Welcome to TRS

.69 to .99v is the spec
And wide open should be 4.5-4.9volt

If you have an OBD2 reader you can look at TPS %
Closed throttle, 15-19%
Wide open, 90% +

So not 0% and 100%
Its a 5volt scale, so 20% would be 1volt, 100% would be 5volts
So you want under 20% closed throttle
and 90% + at wide open

An under $20 Bluetooth OBD2 reader is a good investment, works on any 1996 and newer vehicle, not a Ford thing
And APPS are free, or $5
