I've been driving a Chevrolet for years, and trouble codes popping up is a common occurrence. Simply put, first plug in an OBD scanner to read the specific code—a generic one from Taobao for a few dozen bucks will do. After reading the code, look up its meaning online; for example, P0171 indicates a lean fuel condition. If you can fix it yourself, go ahead—like checking if the oxygen sensor is dirty or replacing spark plugs. Once done, disconnect the negative battery cable for a few minutes to clear the code. But be careful: disconnecting the battery will reset the car locks and radio, so you'll need to reconfigure them. For prevention, regularly cleaning sensor components can reduce the frequency of issues, as Chevrolet models are prone to carbon buildup. Tools and parts aren't expensive, so don't rush to spend money at the dealership—try DIY first.
