Your Buick dealership isn't the only place to buy trusted parts to repair your Rainier. It's not a regular occurrence that you find yourself in need of a replacement Throttle Position Sensor for your car or truck. Make no mistake, you bought your Rainier because you knew that you wanted a variety of special features and American style both rolled up into one vehicle. You bought your Rainier because its dependability and economical pricing appealed to your senses; so why would you be okay with second rate when it comes to the highest quality auto parts?
Constant communication between the ECU and throttle position sensor is required to maintain an ideal balance between fuel efficiency and power output. On your Buick Rainier, the throttle position sensor detects the opening and closing of the butterfly plates inside the throttle body and reports this to the ECU. 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. No matter what, the Buick Rainier throttle position sensor is absolutely critical to your engine performance.
