Ok, I'm a little more sober than I was last night, I'm usually not much help on any given Sunday during football season
TPS = throttle position sensor. It's only function is to tell the ecu the position of the throttle butterfly. This is a pretty important sensor because it tells the ecu some very critical things and it is active from idle to WOT. The ecu takes this reading and uses it to determine load mapping.
There isn't a lot of information available on the KA24E, but the sensors themselves are the same as the KA24DE. The good thing is, the E model is WAY easier to get to check and adjust. There are two screws that secure the TPS to the throttle body. When these are loosened, you can swivel the tps in the slots. This allows for a voltage adjustment. In one of your images it looks like the adjustment is F'd. So at a minimum it requires checking.
Checking is going to require a multimeter. If you don't have one, buy one. I have a really nice one and it has paid for itself in spades. At the very least, pick up a cheap one at harbor freight. They will work just as well for the most part, they just lack a couple of the features that others may have.
Like most things, setting the TPS should be done with the motor at operating temperature. Letting it idle for 5-8 minutes should be fine. Then shut the car off as the test is done with the key in ACC mode.
You'll need 2 paper clips to insert into the back of the TPS plug so you can measure the voltage output. You're looking for .45 to .55 volts. To adjust the TPS, loosen the two 7mm screw/bolts a little, just enough to allow you to move the tps. Leave a little tension on the screws, so once you achieve the voltage you're looking for, the reading won't jump all over as soon as you let go of the tps. It's wicked sensitive and will take a bit of playing with the achieve the correct voltage.
Fortunately for you, there is the cool thing called youtube. On this mysterious site they have video's of just about everything these days. When I was learning how to break stuff...I mean fix stuff stuff, all I had was the FSM and some very poor images. I wish youtube was around back in the day! I was able to track down a couple of video's for ya to make this process even easier.
There are two video's. We're assuming you're tps is good and your wiring is good. These vids go through the entire trouble shooting process, so you don't really need to pay attention until the end of vid 1 and all of vid 2. Watch them all the way through though, it's good info.
