Throttle position sensor

I've gotten a CEL twice on this, how hard is it to change the TPS? And what's a good place to pick one up?

Have you tested the sensor to confirm that it has failed?

The TPS (there are two) is built into the throttle body, and is not normally serviced. If you find the sensors are in fact bad, you can replace the entire unit. Or, if a little more adventurous, parts from another Toyota DBW throttle body can be utilized, you'll need to drill out some rivets to remove the parts.
