TPS Location?

TPS Location?
I had a idle problem when i started my car. It use to drop and turned off. , but after changing my air filter my idle stays. Only now it idles very high.
I am thinking about adjusting the TPS. However, I cant seem to locate the TPS. Can someone please do me a favor and take a picture of where the TPS is located?
Is it possible that the car doesnt have a TPS? Because the previous owner took out a lot of stuff.

It's under the intercooler, so you'll have to warm the car up completely, then take it off to get at it. Now take a short piece of wire and jump the green 2-wire plug next to the leading coil. With the key in the 'ON' position, but the engine off, you can measure voltage at the TPS plug. The plug has 3 wires, and looks like this (sort of):
---
| A |
---------
| B | C |
---------
Measure voltage at pin A. If the engine was warmed up, this value should be 1.0V. If it is not, rotate the TPS adjust screw directly in front of the TPS plunger. The plunger will move in or out depending on the direction you turn it, and the voltage will increase or decrease. Put everything back together and don't forget to remove the wire jumper.
You can find more info on this in the FSM or a Haynes manual.

RotaryRocket88, I think you know a bit too much sir. I've been doing nothing but reading on the second gen. for almost a year in my free time... And, I've nothing on you sir.
Where do you find the time to memorize all of these numbers?!

I've never seen an adjustmen screw like that on an S5 TPS, just the mass adjustment screw on the Tbody that adjusts both the low and high at the same time. My issue is that when I adjust them to get the lights to go off, the high band resistance is a litle bit off. If I adjust it so that the high is in, but now the low is off just a touch. I'm even using the test light. There's no way to slide the switches back and forth on the mount plate as the clip slots are machine so precicley, there's isn't any room. Also a side note on Multimeters. When you're doing adjustment like this or doing resistance checks on pots, use an anolog meter. Digital meters generally use an averaging and it's hard to spot dead spots where with a needled meter you can watch for jumps on the meter.
