How to Change a Throttle Position Sensor in a 2005 Kia Sorentoby Justin Cupler
The throttle position sensor in the 2005 Sorento is responsible for reading the positioning of the valve inside the throttle body and transmitting its reading to the electronic control unit via a change in output voltage. This sensor allows the ECM to adjust the transmission shift points and other important driveline operations in accordance to the positioning of the throttle valve. Replacing a faulty TPS in the 2005 Sorento is a straightforward process that nearly any do-it-yourself mechanic can complete.
Trace the air cleaner outlet tube, the tube connecting the air filter box to the engine, until you reach the throttle body.
Find the throttle position sensor on the rearmost part of the throttle body. Pull upward on the locking tab on the TPS wiring harness and unplug the harness from the TPS. Remove the screws securing the TPS using a Phillips screwdriver and pull the TPS from the throttle body.
Install the new TPS onto the throttle body so its tabs insert into the slots on the throttle body valve. Tighten the TPS screws just until snug with a Phillips screwdriver. Plug the wiring harness into the TPS.
