I ran my codes the other day and got “Throttle position sensor out of range”. I have been trying to test it today and my multimeter is giving me just 0 for my reading. This is a brand new multimeter. I connected the positive to the green wire (dont have any sewing needles to pierce so I dug out an area with a screwdriver) and I placed the ground on my intake. I turned my key to the run position as well. I must be doing something wrong. Any ideas?

Mustang TPS Adjustment - 0.999999v not necessary

EDIT: This post applies to 86-93 5.0 Mustangs. Seems to be a common myth, so lets sticky a thread explaining how the TPS works. Jrichker has provided the basic TPS guideline to follow. I'll just preference it with this. Adjusting your TPS to .99999999 volts is not necessary at all. There...

Do you have a code stored in the computer?
Never mind, went back through the posts,
Let me look for something

Did you open the throttle while the dvm was hooked to the tps?
Clean the connection at the tps pig tail, run test again.

Do you have close to .5v between the orange (to red probe) black wire (to black probe) with the key on?

Disconnect the TPS sensor and prob the orange to black wire. Make sure the key is on. Do you have 5 volts here?

If not, your next task will be to disconnect the 10pin connectors and probe the TPS wire here as well. I do not have the wiring diagrams in front of me to tell you which color connector it is and what wires. But first start at the TPS connector itself. Make sure key is turned to on.

See the graphic for the 10 pin connector circuit layout.


The injector power pin is the VPWR pin in the black 10 pin connector. [/b]
The surging idle checklist has more tps info, see #2, also in the list thread is a pin out of the computer, pretty much everything you need to know, you have to dig around a bit but it's there, daunting read, first time I started working on these I would read stuff over and over, take notes, I also have a 'magic book'.
Thanks to jrichker and the other contributing members for that.
