P0410 is an emission related code. The secondary air injection (AIR) system is designed to lower emission levels after start up. The power train control module (PCM) commands the AIR pump to run for about 1 minute after the engine is started. The heated oxygen sensors (HO2S) and the Short Term Fuel Trim are monitored by the PCM for problems.
If the PCM detects the HO2S and Short Term FT did not respond as expected it sets the P0410 code.
Is the problem continuous or intermittent? Are P0412 or P0418 also set?

NVRL898,
Fault analysis will require access to a scan tool. With a scan tool connected, commands can be sent to the various components of the AIR pump. Using the scan tool, a fault analysis checklist in the Service Manual can check the operation and electrical connections to the AIR pump and sensors.
Have any mosture, water, or debris been injested in the AIR pump? Have any hoses or vacuum hoses been pinched, kinked, heat damaged, or deteriorated? Are there any restrictions in the pump inlet, duct, or filter?
Can you hear any exhaust noise through the air cleaner? If so the AIR solenoid may be leaking vacuum and holding the shut-off valve open.
Is the AIR pump fuse open?
Do the electrical connectors look OK? A poor ground connection for will also cause this fault.
A scan tool and service manual most likely will be needed to isolate the problem if it isn't an obvious vacuum leak, etc.
