3. What is a Throttle Postion Sensor?
• The throttle position sensor in your vehicle serves as a potentiometer (a three-terminal resistor with a
sliding contact that forms an adjustable voltage divider used for measuring electric potential) that sends
variable voltage signals to your cars computer to tell it just how much the throttle plates have been
opened up. The purpose for your throttle position sensor is to provide the engine with the data necessary
to calculate the proper mix of fuel and air needed by the engine at a particular moment for optimal
performance. The throttle position sensor in your vehicle sends a low voltage signal—generally less than 1
volt—to indicate a throttle that is completely closed. Voltage is added as the throttle is opened up. The
maximum amount of volts is generally 5, which tells your main computer that the throttle is completely
open.
• If your car is experiencing acceleration problems, it could be due to a faulty throttle position sensor. If the
sensor is sending the incorrect information about the throttle position to the engine, the engine will not
create the necessary air and fuel mixture. Any miscommunication between the sensor and the engine can
cause your car to hesitate during acceleration, creating a lurching feeling when you drive. A worn down
sensor will often have “dead spots”. These “dead spots” create miscommunication each time the
potentiometer passes them, creating uneven and turbulent acceleration. The most common “dead spot”
is just above the normal idling position, which is why cars often lurch forward when you first press on the
gas pedal. If you are looking for a replacement throttle position sensor, Buy Auto Parts has a full inventory
