The P0171 trouble code on a Chevy Colorado is a general code that can be triggered by various issues. The main culprit is often a faulty vacuum line or a damaged EVAP canister. To detect a vacuum leak, start by visually inspecting all rubber lines connecting to the engine and its parts. Look for any loose or visibly damaged lines. If everything appears to be in good condition, you may need to listen for a faint hissing sound (which can be challenging with the truck running) or have a professional service center conduct a leak test.
