Where do I find the TPS (throttle position sensor) on a 1998 Kia Sephia????

[Cecelia]

Please help.? I have gone to Auto Zone and had the codes read from the check engine light and been told I need to replace the TPS (Throttle Position Sensor) on my 1998 Kia Sephia. I purchased a brand new TPS but can not find the location of the TPS under the hood. Diagrams would be helpful. I would like to repair this ASAP.
