Today I went and got some proper LED's from Radio Shack and made myself a TPS checker.

When I plugged it in, no lights came on. No matter how much I turned the screw no lights came on. Then when I pressed the TPS, the instant I pushed it even a tiny bit, one of the lights would flash. Thats all I could get out of it.

Then I test my voltage on the green/orange wire at the TPS connector. I put my multi on the wire and one on ground. At idle I got 2.4V, and it increased to infinity as I went to WOT.

Is this thing messed up?
Or is it my ECU, my selenoid circuitry thingy's?

And how difficult is it to replace a TPS?
Thanks,

I can't give you a definite answer, because you're measuring in volts.&nbsp If you gave us resistance readings, I could give you a more definite reply - this is why I prefer resistance of voltage measurement.

The TPS should set about 1k&#937 at rest.&nbsp The WOT, it should not go over 6k&#937.&nbsp Checking progressive travel from rest to WOT, it should SMOOTHLY move from 1k&#937 to max reading without jumping to "infinity"/"out-of-range" or short-out to zero.

Ted, how in the hell do you make that omega symbol???

This place allows you to use HTML code.&nbsp I code raw HTML for all my web pages - yeah, I'm a freak. I know the special character display set by prefixing with "&#" then a three digit number code.&nbsp I have a special chart for all this stuff, but I have a bunch I use regularly...

If I need a degree symbol, I use #176 -> &#176
If I need a "squared" symbol, I use #178 -> &#178
If I need the omega symbol for ohms, I use #937 -> &#937

Neat huh?

There is an alternator method if you have an extended keyboard.&nbsp What's an extended keyboard?&nbsp If you've got the numpad on tight right, and a NumLock key, you have an extended keyboard.

You can hold the "Alt" key and punch in almost any three digit combination, and a special character should appear.&nbsp I do NOT have this table memories, but it spits out almost the same special character table that the HTML code spits out.&nbsp The numbers is not the same between HTML and "Alt"...

For example...
HTML code for cents sign is #162 -> &#162
Alt character number is 155 -> "Alt" 1 5 5 -> ¢
You need to have the NumLock ON to have this work.
I can see everyone trying to mess with their keyboards now!
