On the back side of the throttle body/intake manifold, there's a black plastic covering w/ a wire wound coil thing inside of it. It is on the opposite side of where the throttle cable connects to the TB. What is this?

 

TPS sensor

 

yup throttle position sensor

 

Cool, thanks;

Is there anything special I need to know before I try to replace it?

 

Take the voltages from it first since this thing is VERY sensitive to being out of position.

 

From searching, the JDM H22's TPS's were adjustable.

So how do I make sure the new one, prob. from my H23, is positioned right? And if not, is there any way to move/adjust it to be right?

I replaced mine and it was easy. it only goes on one way.

 

so I shouldn't have to do any adjusting?

 

nope

 

how do you remove the TPS, isn't it rivited in there? How did you replace it?

 

you take a dremel w/ a cutting disk and cut a set of slots in their faces like a screw, then screw them out w/a screwdriver
