No it will not affect engine or transmission performance.It will make you fail an OBD2 emission test if you state performs them.If the fuse isn't blown why would you want to replace it?If it was blown you could try just changing it and hope it was just water in the pump.Usually they don't last too long after having water in them any how.You should be able to hear the pump run when you start the engine in the morning.If it does clear the code and see if it resets.
Important: Install the new Secondary Air Injection Pump Outlet Pipe/Hose Assembly to the new Air Pump before installing to the vehicle. This will allow the housing on the hose/pipe assembly to fasten to the pump without damage to one of the holding fasteners.
Important: Located on the inner fender behind the air box there is a oval stamped hole. The new AIR filter must snap into this hole in order for the AIR pump to avoid ingesting water. Removal of the Air Cleaner Assembly may be necessary.
Notice: Secure the new AIR pump inlet hose and filter into the opening on the inner fender as shown above. If the filter is not properly secure to the inner fender repeat Non-Function Air pump may occur from ingesting water.
