There are a lot of possibilities. A P0410 is a secondary air injection fault code. This code will not affect the engine running. The code can be caused by a faulty secondary air injection pump or a vacuum leak to the diverter valves or switchover valve to the system or a fault with any of those valves or with the relay for the system or by plugged secondary air injection passages in the cylinder heads. The code can even be caused by a faulty oxygen sensor.
Please let me know if you have any questions.
