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 Buick Regal, the throttle position sensor reads how far open the butterfly plates are inside the throttle body and tells the ECU how to respond. 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 Regal throttle position sensor.
