What Throttle Position Sensor does for your vehicle.

Your fuel-injected engine requires constant communication between the engine control module and the throttle position sensor to maintain the best balance between power and gas mileage. The throttle position sensor on your Saturn Ion 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, the Saturn Ion throttle position sensor is absolutely critical to your engine performance.
