The Toyota 22R-E (and R-EC) engines use a "Linear" throttle position sensor. The throttle position sensor is a power resistor located on the throttle body, and it carries out the function it has the purpose of feeding data to your engine control unit despite the level at which the throttle valve is open. If you are looking for information on the location of a throttle position sensor, you have landed on the right page. Fig. Your gas pedal is attached to the the throttle valve (either electronically or mechanically) — as you press the pedal farther in, the valve opens more. Another symptom to determine that a throttle position sensor is malfunctioning is the uneven idling of the car or jerking and hesitant stopping of it. 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. Some engine control units (ECUs) also control the throttle position electronic throttle control (ETC) or "drive by wire" systems, and if that is done, the position sensor is used in a feedback loop to enable that control.[1].
