Volvo S70 Problem
Average Mileage: 146,367 mi (83,543 mi - 223,000 mi)
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.

Check engine light due to failed secondary air pump. Check valve failure also.

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
