The P1133 code for a Volvo S80 typically indicates an issue with the air-fuel mixture, specifically that the engine control module (ECM) has detected a lean condition in the engine's operation. This can be caused by various factors such as a malfunctioning oxygen sensor, vacuum leaks, or fuel delivery issues. It's important to diagnose the underlying cause accurately to avoid further engine problems. Addressing this code often involves checking the fuel system, air intake components, and sensors for proper functioning.
