Your resistance readings are on the high side indicating a possible sensor problem. But you didn't get a 4-1-1 so the ECU might be handling this situation.

First: your 1-1-3 code. Check the air hose from the air filter to the throttle body for cracks or other leaks. Also check the vacuum tree for the same. Unmetered air coming into the intake manifold will give you this code.

Now, the TPS. Your testing has me a little confused. The 3-3-2 only happens when the throttle is closed, idle. The 3-3-3 is at WOT. There is nothing between or when the throttle leaves either position.
I would get the TPS squeeky clean and reinstall it and clean up the air leak before any more testing.
