The P0171 code in a Volvo S40 indicates a lean air-fuel mixture, typically caused by a vacuum leak, a faulty mass air flow (MAF) sensor, or a malfunctioning fuel system. To fix it, start by inspecting vacuum hoses for leaks and ensuring all connections are secure. Next, check the MAF sensor for proper functioning and clean or replace it if necessary. Lastly, inspect the fuel injectors and fuel pressure to ensure they are operating correctly, addressing any issues found.
