I recently bought my 98 volvo s70 from a guy that had pulled out the check engine light. Well comes to find out that i am throwing 10 codes and had to do with the smog pump/air pump

This is an easy fix. Check valve fails, condesation enters pump, bearings freeze, shazam CEL light is on. Air pump is under battery tray. Buy a rebuilt pump with warrenty on ebay ~$150. Buy a new check valve ~$50. Buy a new relay (#2 in main fuse box) ~$20. Replace parts. Done.

Air pump whining loudly for several months when first started, then abruptly stopped with CEL.
Air pump failed due to moisture from failed check valve
