Question moved to model category.

This is a strange code that doesn't appear to have one definitive reason, it's a bit of "you have a bit of a problem, but we aren't sure". Just Answer dot com mechanic says it is the MAF Sensor.

Po133 is and oxygen sensor code. Replace the front oxygen sensor use a bosch or OE sensor only. P0442 is and evap system leak. Most common fault is a cracked hose at the evap cannister at the right rear of the car.

check head gasket and also check inlet manifold for cracks or inlet gasket

All S70's have a 2.4 liter. There should be a numbers like 2.4 or 2400cc or something like that. The 7th and 8th vin digit is the engine. 55 is a B 2454 S engine. If unsure call the dealer parts dept and they can tell you, based on the VIN number.

The fuel filter can be located under the carpeted cargo storage floor at the rear of the wagon. Remove the four 10mm bolts, remove the cover. You will then see a removable plate to the right just behind the rear passenger seat. Fuel filter can be seen through hole in hole. Replaced from underneath wagon. Be sure to make sure lines are fully inserted onto filter. Check for leaks. Note arrow on filter for correct fuel flow. Good luck and hope this helps and no smoking please LOL
