Engine Check light turned on. on 1998 Volvo S70

Advantage auto parts ran diagnostic on ODII. Code showed Po410 ... secondary air injector. what the heck does this mean?

Asked by for the 1998 Volvo S70
This system is known for having issues with the air pump check valve, and when it fails it allows moisture to contaminate the air pump too, so it's likely both will need replacement. You'll want to take this to a Volvo shop, they will be very familiar with this issue.
