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 Buick Riviera reads how far open the butterfly plates are inside the throttle body and reports this to the ECU. 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. Either way, the Buick Riviera throttle position sensor is absolutely critical to your engine performance.
