Code P2187 on a 2005 Volvo S60 indicates a "System Too Lean at Idle (Bank 1)" condition. This means that the engine control module (ECM) has detected that the air-fuel mixture is too lean when the engine is idling. Common causes for this code include vacuum leaks, faulty fuel injectors, a failing mass air flow sensor, or issues with the fuel system. It's advisable to inspect these components to diagnose and resolve the issue effectively.
