Most check engine light faults are related to a vacuum leak in the system. It could be as simple as a loose gas cap. In my case, and the majority of other S70's, there is a small vacuum hose elbow, located out of sight from the engine manifold and behind the engine thermostat housing, that has deteriorated and is most likely setting the code in your vehicle for a fault. It is not easy to get to and will take some effort to replace. You can go to Autozone and they can read the code for you to see if you're going in the right direction. If it is a gross vacuum leak as determened by the code, then look a the rubber elbows/hoses in the charcoal vapor canistor vacuum circuit. Check out some of the forums such as Mathews or Bay13 for technical inof on the actual repairs.

Your engine's computer is seeing data from the engine that it considers out of the normal on your vehicle. Any automotive repair shop will be able to scan the computer for the trouble code for you. Autozone will scan the code for free, however, you will still need to bring the trouble code print-out to a well qualified technician to be able to tell you what the potential problem may be. These codes can indicate anything from a loose gas cap to random misfire in the engine.
