Default Where is the TPS?

After removing the intake manifold to replace the sparkplugs, my car started throwing some errors about a bad TPS. I think I may not have plugged something in all the way or something. Does anyone have a picture where the TPS is?

Thanks!

It's right in the throttle body. A single connector goes to it, controlling the throttle motor, and both throttle-position-sensors (VTA1 and VTA2).

Check the connector on your throttle body.

Ah, duh. Makes sense. Thanks!

I did clean my TB. Sprayed some TB cleaner in it, wiped as much of the carbon as I could out. Could cleaning cause any sort of issues?

Not usually, but if some got through the shaft into the TPS area, it may effect the TPS readings, but it's hard to say 100%.

Is it ok to take it apart? It looked like a nicely built TB, and not sure if I need to be a master tech to service it... I guess I'll just first fiddle around with the connection. Make sure that's ok.

But I did want to mention that other than the light, everything is running perfectly fine, as far as I can tell. Acceleration, idle, is all good.
