Kinda important - Before removing the old throttle position sensor, snap a photo of its position with your phone and try to match the old one's position as closely as you can since there is a little 'play' in how you can position the sensor.
It may not be that big a deal though because I didn't check mine beforehand, and I just eyeballed the new one, and it worked fine, passed emissions.
This shows how to replace a 2002-2005 Kia Sedona throttle position sensor (TPS).
The Kia Sedona is well known for having issues with bad throttle position sensors.
Symptoms of a bad throttle position sensor: engine surging/bogging down and uneven jumpiness during acceleration.
They go for about $100 at AutoZone.
Fix should take about 5 minutes. And is something you can do yourself.
