Hello. What is the year and model of your Kia? I apologize if you already provided that information, but it's not showing up for me.

Customer: replied 8 months ago.
2005 Kia Sedona. I understand now that the sensor needs adjusted but can't find the correct value.
Expert:  AZTechBrian replied 8 months ago.

The standard value for the throttle position sensor is between 300 and 900 mV.

Customer: replied 8 months ago.
Anywhere in that range is fine?
Expert:  AZTechBrian replied 8 months ago.

That is what the adjustment procedure is stating, yes. Is it within that range and still producing a problem?

Customer: replied 8 months ago.
I couldn't find a way to get a voltage reading, There are no accessible wires. I adjusted it so that the engine idled like normal and it seems to run fine now.
Expert:  AZTechBrian replied 8 months ago.

If it's running fine now, then you are almost definitely within specification. Here is a link however to a file in my dropbox that should help you quite a bit in case you need it. The second image shows the procedure done with a DVOM. You could use push pins directly into the back of the connector (that's what we do) Click the blue link below. If you have any further questions please feel free to ask. If not please remember to rate me. You can always follow up if needed at any time even after rating.
