DTC P0410: Secondary Air Injetion System
The Powertrain Control Module (PCM) activates the Secondary Air Injection system by grounding both the AIR pump relay and the AIR vacuum control solenoid control circuits. The AIR pump adds air to the exhaust stream to lower emissions. It does this by taking in outside air and pumping it through two one-way check valves into each bank of the exhaust.
About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in the northeast with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse. Sometimes replacing the fuse will fix all your problems and you are all set until next winter when it all happens again.
Also, sometimes water is allowed to enter the pump through the intake side of the system and ruins the system that way. Blowing out the water may or may not cure the problem.
You will need to inspect the AIR system to see what exactly is defective and needing replaced.
