P0410 Secondary Air Injection System
"Secondary Air" is an abbreviated term for the "Secondary Air Injection System". This system uses a separate air pump and a series of metal and rubber tubes to force outside air into the exhaust stream and help the catalytic converter burn away excessive emissions.

Possible causes and fixes are:
#1 Poor connection, rubbed-through wire insulation or a broken wire inside the insulation.

#2 Inspect harness connectors for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal-to-wire connection, and damaged harness.

#3 Check for worn or loose AIR pump drive belt.

#4 Check for pinched, kinked or restricted AIR pipes, hoses or fittings.

Problems with this system can stem from electrical circuits, solenoids, or switches that control the pump and valves. Other problems include sticking valves, loose, rusted, or poorly connected lines, a broken drive belt, or possibly a bad pump.

Hope this leads you in the right direction.
