Secondary air flow problem

I am getting a secondary air flow code on my 98 E320 4matic. I unplugged the air pump and connected it to a 12v source, and it appears to work fine. Anyone care to suggest what might be next? A solenoid? Relay? Leaky hose?

Thanks,

Steve

Thanks. I'll look at the P40 relay and then I guess I will replace the O2 sensors. One of the cats is rattling so I might as well do everything at once.
