Throttle Position Sensor

On electronic fuel injected engines and computer-controlled transmissions, accelerator pedal position is important. Whether at idle, part-throttle, or wide-open throttle, this driver input is critical in letting the transmission know whether to hold in a gear longer or shift into overdrive, for example. In fuel injection applications, throttle position is important for fuel and ignition mapping to provide the best performance and fuel mileage. To help provide this data, a throttle position sensor is used. This small electrical component has a spring lever that connects and moves with the throttle on either a carburetor or throttle body. The lever position in the sensor is converted to an electrical voltage signal that is sent to the engine or transmission computer. The information is then added to the calculation on how adjustments are made to either the fuel, ignition, or transmission behavior. Over time this component can wear and fail from age and use. Aftermarket options are needed for custom fuel injection or for adding a late model transmission to a carbureted engine setup.

When choosing a replacement throttle position sensor, first confirm the year, make, model, engine, and transmission of your vehicle. Then find the compatible throttle position sensors for your application. For custom applications, confirm the fuel injection or transmission type as well as mounting design to ensure proper fitment and operation.
