You should have a check engine light illuminated. If so check the codes.
The throttle position sensor (TPS) on a Kia Sedona is typically located on the throttle body, which is situated between the air intake manifold and the engine. To access it, you may need to remove any engine covers or components obstructing the throttle body. The sensor is usually mounted directly on the throttle body and has an electrical connector attached to it. Always refer to the vehicle’s service manual for specific details and instructions related to your model year.

A camshaft position sensor detects which cylinder is firing and establishes the coil firing sequence. In a Kia Sedona, it is located at the end of the intake camshaft.
From the Kia Technical Service Bulletin: Download provides information related to the Throttle Position Sensor (TPS) for Sorento & Sedona models. Some Sorento & Sedona vehicles may exhibit diagnostic trouble codes P0121 and/or P1121. This condition mainly occurs in high ambient or desert areas, and can be related to the occasional increase in contact resistance due to excessive wear of the inner elements of the TP sensor. This bulletin describes the proper service and adjustment procedure for replacing the TP Sensor. - Effective Vehicle Information 2003-2006 Sorento 3.5L 2002-2005 Sedona 3.5L - Parts Information Part Name Previous Part No. New Part No. Throttle Position Sensor 35102 39000 35102 39000FFF - Service Procedure Replacement Procedure: 1. Turn ignition OFF. Remove engine cover and disconnect electrical connector from TP Sensor. 2. Remove two (2) retaining screws from TP Sensor and remove from throttle body. 3. Install new TP Sensor to throttle body. Install retaining screws and hand tighten lightly. Adjustment will be required. Re-install electrical connector to TP Sensor. 4. Install Global Diagnostic System. a. Select "System Option" b. Select "Idle RPM Adjust Mode" c. Apply Parking Brake 5. Select Neutral position and place engine in idle condition with A/C OFF. 6. Remove rubber plug and adjust using instructions provided on screen. Adjust TPS: 7. Using the GDS scan tool, monitor current data using two (2) parameters: • Closed Throttle Position Switch • Throttle Position Voltage Value 8. Open throttle by hand very slowly until idle switch status switches to OFF. Note the TPS voltage value. Voltage: 9. Close throttle and record the TPS voltage. Voltage: Closed throttle voltage should be 30~65mV less than the voltage noted in step eight (8). Adjust TP Sensor and repeat test as required.
Mind died on me and I replced the battery. Had to clean the inside and it worked fine.
well it depends on the model of Kia, sideways or rear wheel drive, but generally TPS sensor is mounted on the throttle dody , some on the top , most on the side. On my 02 Sedona.
