Engine light code P0171 for a 2006 GMC Envoy indicates that the engine control module (ECM) has detected a lean fuel condition in Bank 1, meaning there is too much air or not enough fuel in the combustion mixture. This can be caused by issues such as a vacuum leak, a faulty mass airflow sensor, or fuel delivery problems. It's important to diagnose and address the underlying cause to prevent potential engine performance issues.
