PO 410 engine code secondary air injection V70-XC70 1998

Have you checked the pump for water? The way the system is desigined (volvo engineers didn't figure in that water runs down hill), the pump gradually fills with water eventually shorting it out. As the water collects in the outflow section, you may have enough there to restrict flow. Just a thought. Mine has about a half pint of water inside before it shorted out so I know it had to be obstructing the outflow. Can try drilling 1/8th " drain hole and see what runs out or remove it and dump it out.
