Buick automobile enthusiasts have become used to a certain level of reliability when driving their Rainier around town. The vehicle in your driveway is head and shoulders above the rest compared to all the other cars, trucks, and SUVs currently being driven today. Make no mistake, you didn't buy your Rainier unless you wanted to buy a variety of special features and American style both impeccably combined into one car, truck, or SUV. Anyone who owns a Buick knows that when it comes to maintaining their automobile only the most superior replacement parts will do.
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. On your Buick Rainier, the throttle position sensor 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. It goes without saying, your engine's performance really depends on the Buick Rainier throttle position sensor.
