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. The throttle position sensor on your Buick LaCrosse detects the opening and closing of the butterfly plates inside the throttle body and the engine control unit determines the appropriate response. At wide open throttle it may downshift and flood the fuel injectors for more power, or reduce fuel consumption when you let off the accelerator. It goes without saying, your engine's performance really depends on the Buick LaCrosse throttle position sensor.
