A code P0410 may mean that one or more of the following has happened:

Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump
Blown AIR pump fuse due to freezing up
Possible SolutionsNote: There is a technical service bulletin (TSB) regarding this code for a number of GM models. The TSB calls for the replacement of the AIR pump and the installation of a new secondary injection hose. The TSB can be found on this ACDelco site.

Additionally, if you simply replace the AIR pump the problem may return again (and again). If you replace the pump, also clean out the hoses and replace the one-way check valve. If this is on a GM model that the TSB applies to, follow those instructions in the link above. In a few cases, people have put a small hole in the rubber cover on the pump which allows any water to drain out.

Also, please note that this may be covered under the emissions warranty on the vehicle. If your vehicle is out of bumper-to-bumper warranty, check if the emissions warranty is still valid!

Replace the AIR pump AND one-way check valve
Test and clean the AIR pump AND test and replace the one-way air check valve
Replace the AIR pump inlet hose
Replace the AIR pump fuse (found under the hood)
