In order to achieve an optimum balance between fuel economy and horsepower, your fuel-injected engine requires constant communication between its engine control unit and the throttle position sensor. On your GMC Sierra 1500 HD, the throttle position sensor detects the opening and closing of the butterfly plates inside the throttle body and the engine control unit determines the appropriate response. It may lower the amount of fuel being sent to the injectors, or it may downshift the transmission and give you a boost of power. No matter what, your engine's performance really depends on the GMC Sierra 1500 HD throttle position sensor.
